e835d150b1 exfat: support handle zero-size directory
[ Upstream commit dab48b8f2fe7264d51ec9eed0adea0fe3c78830a ]

After repairing a corrupted file system with exfatprogs' fsck.exfat,
zero-size directories may result. It is also possible to create
zero-size directories in other exFAT implementation, such as Paragon
ufsd dirver.

As described in the specification, the lower directory size limits
is 0 bytes.

Without this commit, sub-directories and files cannot be created
under a zero-size directory, and it cannot be removed.

c7f514e266 crypto: hisilicon/qm - prevent soft lockup in receive loop
[ Upstream commit 33fc506d2ac514be1072499a263c3bff8c7c95a0 ]

In the scenario where the accelerator business is fully loaded.
When the workqueue receiving messages and performing callback
processing, there are a large number of messages that need to be
received, and there are continuously messages that have been
processed and need to be received.
This will cause the receive loop here to be locked for a long time.
This scenario will cause watchdog timeout problems on OS with kernel
preemption turned off.

The error logs:
watchdog: BUG: soft lockup - CPU#23 stuck for 23s! [kworker/u262:1:1407]
[ 1461.978428][   C23] Call trace:

Therefore, it is necessary to add an actively scheduled operation in the

80be0425ee ASoC: Intel: soc-acpi-cht: Add Lenovo Yoga Tab 3 Pro YT3-X90 quirk
[ Upstream commit 2cb54788393134d8174ee594002baae3ce52c61e ]

The Lenovo Yoga Tab 3 Pro YT3-X90 x86 tablet, which ships with Android with
a custom kernel as factory OS, does not list the used WM5102 codec inside
its DSDT.

Workaround this with a new snd_soc_acpi_intel_baytrail_machines[] entry
which matches on the SST id instead of the codec id like nocodec does,
combined with using a machine_quirk callback which returns NULL on
other machines to skip the new entry on other machines.

It's LINK_CAPABILITIES_REG.PCIE_CAP_MAX_LINK_WIDTH. If it isn't done at

[ Upstream commit a9a1bcba90254975d4adbcca53f720318cf81c0c ]

This is a preparation before adding the Max-Link-width capability
setup which would in its turn complete the max-link-width setup
procedure defined by Synopsys in the HW-manual.

Seeing there is a max-link-speed setup method defined in the DW PCIe
core driver it would be good to have a similar function for the link
width setup.

That's why we need to define a dedicated function first from already
implemented but incomplete link-width setting up code.

Place IRQ handlers such as gic_handle_irq() in the irqentry section even
if FUNCTION_GRAPH_TRACER is not enabled.  Without this, the stack
depot's filter_irq_stacks() does not correctly filter out IRQ stacks in
those configurations, which hampers deduplication and eventually leads
to "Stack depot reached limit capacity" splats with KASAN.

A similar fix was done for arm64 in commit f6794950f0e5ba37e3bbed

[ Upstream commit 46a0a2c96f0f47628190f122c2e3d879e590bcbe ]

Built-in firmware of cptkbd handles scrolling by itself (when middle
button is pressed) but with issues: it does not support horizontal and
hi-res scrolling and upon middle button release it sends middle button
click even if there was a scrolling event. Commit 3cb5ff0220e3 ("HID:
lenovo: Hide middle-button press until release") workarounds last
issue but it's impossible to workaround scrolling-related issues
without firmware modification.

Likely, Dennis Schneider has reverse engineered the firmware and
provided an instruction on how to patch it [1]. However,
aforementioned workaround prevents userspace (libinput) from knowing
exact moment when middle button has been pressed down and performing
"On-Button scrolling". This commit detects correctly-behaving patched
firmware if cursor movement events has been received during middle
button being pressed and stops applying workaround for this device.

1a7c53fdea fs/jfs: Add check for negative db_l2nbperpage
[ Upstream commit 525b861a008143048535011f3816d407940f4bfa ]

l2nbperpage is log2(number of blks per page), and the minimum legal
value should be 0, not negative.

In the case of l2nbperpage being negative, an error will occur
when subsequently used as shift exponent.

Syzbot reported this bug:

UBSAN: shift-out-of-bounds in fs/jfs/jfs_dmap.c:799:12
shift exponent -16777216 is negative

8bbe784c2f scsi: ibmvfc: Remove BUG_ON in the case of an empty event pool
[ Upstream commit b39f2d10b86d0af353ea339e5815820026bca48f ]

In practice the driver should never send more commands than are allocated
to a queue's event pool. In the unlikely event that this happens, the code
asserts a BUG_ON, and in the case that the kernel is not configured to
crash on panic returns a junk event pointer from the empty event list
causing things to spiral from there. This BUG_ON is a historical artifact
of the ibmvfc driver first being upstreamed, and it is well known now that
the use of BUG_ON is bad practice except in the most unrecoverable
scenario. There is nothing about this scenario that prevents the driver
from recovering and carrying on.

Remove the BUG_ON in question from ibmvfc_get_event() and return a NULL
pointer in the case of an empty event pool. Update all call sites to
ibmvfc_get_event() to check for a NULL pointer and perfrom the appropriate
failure or recovery action.

372636debe crypto: pcrypt - Fix hungtask for PADATA_RESET
[ Upstream commit 8f4f68e788c3a7a696546291258bfa5fdb215523 ]

We found a hungtask bug in test_aead_vec_cfg as follows:

INFO: task cryptomgr_test:391009 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

 Kernel panic - not syncing: hung_task: blocked tasks

For padata_do_parallel, when the return err is 0 or -EBUSY, it will call
wait_for_completion(&wait->completion) in test_aead_vec_cfg. In normal
case, aead_request_complete() will be called in pcrypt_aead_serial and the
return err is 0 for padata_do_parallel. But, when pinst->flags is
PADATA_RESET, the return err is -EBUSY for padata_do_parallel, and it
won't call aead_request_complete(). Therefore, test_aead_vec_cfg will
hung at wait_for_completion(&wait->completion), which will cause
hungtask.

The problem comes as following:
(padata_do_parallel)                 |
    rcu_read_lock_bh();              |
    err = -EINVAL;                   |   (padata_replace)
                                     |     pinst->flags |= PADATA_RESET;
    err = -EBUSY                     |
    if (pinst->flags & PADATA_RESET) |
        rcu_read_unlock_bh()         |
        return err

In order to resolve the problem, we replace the return err -EBUSY with
-EAGAIN, which means parallel_data is changing, and the caller should call
it again.

v3:
remove retry and just change the return err.
v2:
introduce padata_try_do_parallel() in pcrypt_aead_encrypt and
pcrypt_aead_decrypt to solve the hungtask.

66a492c766 ASoC: cs35l56: Use PCI SSID as the firmware UID
[ Upstream commit 1a1c3d794ef65ef2978c5e65e1aed3fe6f014e90 ]

If the driver properties do not define a cirrus,firmware-uid try to get the
PCI SSID as the UID.

On PCI-based systems the PCI SSID is used to uniquely identify the specific
sound hardware. This is the standard mechanism for x86 systems and is the
way to get a unique system identifier for systems that use the CS35L56 on
SoundWire.

For non-SoundWire systems there is no Windows equivalent of the ASoC driver
in I2C/SPI mode. These would be:

1. HDA systems, which are handled by the HDA subsystem.
2. Linux-specific systems.
3. Composite devices where the cs35l56 is not present in ACPI and is
   configured using software nodes.

Case 2 can use the firmware-uid property, though the PCI SSID is supported
as an alternative, as it is the standard PCI mechanism.

Case 3 is a SoundWire system where some other codec is the SoundWire bridge
device and CS35L56 is not listed in ACPI. As these are SoundWire systems
they will normally use the PCI SSID.

17560515ae ASoC: SOF: Pass PCI SSID to machine driver
[ Upstream commit ba2de401d32625fe538d3f2c00ca73740dd2d516 ]

Pass the PCI SSID of the audio interface through to the machine driver.
This allows the machine driver to use the SSID to uniquely identify the
specific hardware configuration and apply any platform-specific
configuration.

struct snd_sof_pdata is passed around inside the SOF code, but it then
passes configuration information to the machine driver through
struct snd_soc_acpi_mach and struct snd_soc_acpi_mach_params. So SSID
information has been added to both snd_sof_pdata and
snd_soc_acpi_mach_params.

PCI does not define 0x0000 as an invalid value so we can't use zero to
indicate that the struct member was not written. Instead a flag is
included to indicate that a value has been written to the
subsystem_vendor and subsystem_device members.

sof_pci_probe() creates the struct snd_sof_pdata. It is passed a struct
pci_dev so it can fill in the SSID value.

sof_machine_check() finds the appropriate struct snd_soc_acpi_mach. It
copies the SSID information across to the struct snd_soc_acpi_mach_params.
This done before calling any custom set_mach_params() so that it could be
used by the set_mach_params() callback to apply variant params.

The machine driver receives the struct snd_soc_acpi_mach as its
platform_data.

c766264e0e ASoC: soc-card: Add storage for PCI SSID
[ Upstream commit 47f56e38a199bd45514b8e0142399cba4feeaf1a ]

Add members to struct snd_soc_card to store the PCI subsystem ID (SSID)
of the soundcard.

The PCI specification provides two registers to store a vendor-specific
SSID that can be read by drivers to uniquely identify a particular
"soundcard". This is defined in the PCI specification to distinguish
products that use the same silicon (and therefore have the same silicon
ID) so that product-specific differences can be applied.

PCI only defines 0xFFFF as an invalid value. 0x0000 is not defined as
invalid. So the usual pattern of zero-filling the struct and then
assuming a zero value unset will not work. A flag is included to
indicate when the SSID information has been filled in.

Unlike DMI information, which has a free-format entirely up to the vendor,
the PCI SSID has a strictly defined format and a registry of vendor IDs.

It is usual in Windows drivers that the SSID is used as the sole identifier
of the specific end-product and the Windows driver contains tables mapping
that to information about the hardware setup, rather than using ACPI
properties.

This SSID is important information for ASoC components that need to apply
hardware-specific configuration on PCI-based systems.

As the SSID is a generic part of the PCI specification and is treated as
identifying the "soundcard", it is reasonable to include this information
in struct snd_soc_card, instead of components inventing their own custom
ways to pass this information around.

remain in a HIGH state even when audio is disabled. Linking pinctrl with
DAPM using SND_SOC_DAPM_PINCTRL will ensure that audio pins remain in
GPIO mode by default and only switch to an audio function when necessary.

Wrap the usb controllers in an intermediate simple-bus and use it to
constrain the dma address size of these usb controllers to the 40b
that they generate toward the interconnect. This is required because
the SoC uses 48b address sizes and this mismatch would lead to smmu
context faults [1] because the usb generates 40b addresses while the
smmu page tables are populated with 48b wide addresses.

bce7b184f2 soc: qcom: pmic: Fix resource leaks in a device_for_each_child_node() loop
[ Upstream commit 5692aeea5bcb9331e956628c3bc8fc9afcc9765d ]

The device_for_each_child_node loop should call fwnode_handle_put()
before return in the error cases, to avoid resource leaks.

Let's fix this bug in pmic_glink_altmode_probe().

b58ace0e8c drm/amd/display: fix num_ways overflow error
[ Upstream commit 79f3f1b66753b3a3a269d73676bf50987921f267 ]

[Why]
Helper function calculates num_ways using 32-bit.  But is
 returned as 8-bit.  If num_ways exceeds 8-bit, then it
 reports back the incorrect num_ways and erroneously
 uses MALL when it should not

[How]
Make returned value 32-bit and convert after it checks
 against caps.cache_num_ways, which is under 8-bit

ba3c0796d2 drm/amdgpu: Fix a null pointer access when the smc_rreg pointer is NULL
[ Upstream commit 5104fdf50d326db2c1a994f8b35dcd46e63ae4ad ]

In certain types of chips, such as VEGA20, reading the amdgpu_regs_smc file could result in an abnormal null pointer access when the smc_rreg pointer is NULL. Below are the steps to reproduce this issue and the corresponding exception log:

1. Navigate to the directory: /sys/kernel/debug/dri/0
2. Execute command: cat amdgpu_regs_smc

1afe397315 drm/panel: st7703: Pick different reset sequence
[ Upstream commit d12d635bb03c7cb4830acb641eb176ee9ff2aa89 ]

Switching to a different reset sequence, enabling IOVCC before enabling
VCC.

There also needs to be a delay after enabling the supplies and before
deasserting the reset. The datasheet specifies 1ms after the supplies
reach the required voltage. Use 10-20ms to also give the power supplies
some time to reach the required voltage, too.

This fixes intermittent panel initialization failures and screen
corruption during resume from sleep on panel xingbangda,xbd599 (e.g.
used in PinePhone).
