commit 75e9a330a9bd48f97a55a08000236084fe3dae56 upstream.
nand_release() is supposed be called after MTD device registration.
Here, only nand_scan() happened, so use nand_cleanup() instead.
There is no real Fixes tag applying here as the use of nand_release()
in this driver predates by far the introduction of nand_cleanup() in
commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. However, pointing this commit as the
culprit for backporting purposes makes sense even if this commit is not
introducing any bug.

Not sure nand_cleanup() is the right function to call here but in any
case it is not nand_release(). Indeed, even a comment says that
calling nand_release() is a bit of a hack as there is no MTD device to
unregister. So switch to nand_cleanup() for now and drop this
comment.

commit 1d5d08ee9b28cff907326b4ad5a2463fd2808be1 upstream.
During ONFI detection, the CRC derived from the parameter page and the
CRC supposed to be at the end of the parameter page are compared. If
they do not match, the second then the third copies of the page are
tried.
The current implementation compares the newly derived CRC with the CRC
contained in the first page only. So if this particular CRC area has
been corrupted, then the detection will fail for a wrong reason.
Fix this issue by checking the derived CRC against the right one.

commit f354157a7d184db430c1a564c506434e33b1bec5 upstream.
Currently, for EINT_TYPE GPIOs, the CON and FLTCON registers
are saved and restored over a suspend/resume cycle. However, the
EINT_MASK registers are not.
On S5PV210 at the very least, these registers are not retained over
suspend, leading to the interrupts remaining masked upon resume and
therefore no interrupts being triggered for the device. There should
be no effect on any SoCs that do retain these registers as theoretically
we would just be re-writing what was already there.

commit 165ae7a8feb53dc47fb041357e4b253bfc927cf9 upstream.
igb device gets runtime suspended when there's no link partner. We can't
get correct speed under that state:
$ cat /sys/class/net/enp3s0/speed
1000
In addition to that, an error can also be spotted in dmesg:
[ 385.991957] igb 0000:03:00.0 enp3s0: PCIe link lost
Since device can only be runtime suspended when there's no link partner,
we can skip reading register and let the following logic set speed and
duplex with correct status.
The more generic approach will be wrap get_link_ksettings() with begin()
and complete() callbacks. However, for this particular issue, begin()
calls igb_runtime_resume() , which tries to rtnl_lock() while the lock
is already hold by upper ethtool layer.
So let's take this approach until the igb_runtime_resume() no longer
needs to hold rtnl_lock.

Since the driver was first introduced into the kernel, it has only
handled the ciphers associated with WEP, WPA, and WPA2. It fails with
WPA3 even though mac80211 can handle those additional ciphers in software,
b43legacy did not report that it could handle them. By setting MFP_CAPABLE using
ieee80211_set_hw(), the problem is fixed.
With this change, b43legacy will handle the ciphers it knows in hardware,
and let mac80211 handle the others in software. It is not necessary to
use the module parameter NOHWCRYPT to turn hardware encryption off.
Although this change essentially eliminates that module parameter,
I am choosing to keep it for cases where the hardware is broken,
and software encryption is required for all ciphers.

This patch fixes commit 75388acd0cd8 ("add mac80211-based driver for
legacy BCM43xx devices")
In https://bugzilla.kernel.org/show_bug.cgi?id=207093, a defect in
b43legacy is reported. Upon testing, thus problem exists on PPC and
X86 platforms, is present in the oldest kernel tested (3.2), and
has been present in the driver since it was first added to the kernel.
The problem is a corrupted channel status received from the device.
Both the internal card in a PowerBook G4 and the PCMCIA version
(Broadcom BCM4306 with PCI ID 14e4:4320) have the problem. Only Rev, 2
(revision 4 of the 802.11 core) of the chip has been tested. No other
devices using b43legacy are available for testing.
Various sources of the problem were considered. Buffer overrun and
other sources of corruption within the driver were rejected because
the faulty channel status is always the same, not a random value.
It was concluded that the faulty data is coming from the device, probably
due to a firmware bug. As that source is not available, the driver
must take appropriate action to recover.
At present, the driver reports the error, and them continues to process
the bad packet. This is believed that to be a mistake, and the correct
action is to drop the correpted packet.

commit e0a851fe6b9b619527bd928aa93caaddd003f70c upstream.
If the call to uart_add_one_port() in serial8250_register_8250_port()
fails, a half-initialized entry in the serial_8250ports[] array is left
behind.
A subsequent reprobe of the same serial port causes that entry to be
reused. Because uart->port.dev is set, uart_remove_one_port() is called
for the half-initialized entry and bails out with an error message:
bcm2835-aux-uart 3f215040.serial: Removing wrong port: (null) != (ptrval)
The same happens on failure of mctrl_gpio_init() since commit
4a96895f74c9 ("tty/serial/8250: use mctrl_gpio helpers").
Fix by zeroing the uart->port.dev pointer in the probe error path.
The bug was introduced in v2.6.10 by historical commit befff6f5bf5f
("[SERIAL] Add new port registration/unregistration functions."):
https://git.kernel.org/tglx/history/c/befff6f5bf5f
The commit added an unconditional call to uart_remove_one_port() in
serial8250_register_port(). In v3.7, commit 835d844d1a28 ("8250_pnp:
do pnp probe before legacy probe") made that call conditional on
uart->port.dev which allows me to fix the issue by zeroing that pointer
in the error path. Thus, the present commit will fix the problem as far
back as v3.7 whereas still older versions need to also cherry-pick
835d844d1a28.

commit a8876c22eab9a871834f85de83e98bbf7e6e264d upstream.
Previously, the output format was programmed as part of the ioctl()
handler. However, this has two problems:
1) If there are multiple active streams with different output
formats, the hardware will use whichever format was set last
for both streams. Similarly, an ioctl() done in an inactive
context will wrongly affect other active contexts.
2) The registers are written while the device is not actively
streaming. To enable runtime PM tied to the streaming state,
all hardware access needs to be moved inside cedrus_device_run().
The call to cedrus_dst_format_set() is now placed just before the
codec-specific callback that programs the hardware.

commit d601afcae2febc49665008e9a79e701248d56c50 upstream.
It's an error if the value of the RX/TX tail descriptor does not match
what was written. The error condition is true regardless the duration
of the interference from ME. But the driver only performs the reset if
E1000_ICH_FWSM_PCIM2PCI_COUNT (2000) iterations of 50us delay have
transpired. The extra condition can lead to inconsistency between the
state of hardware as expected by the driver.
Fix this by dropping the check for number of delay iterations.
While at it, also make __ew32_prepare() static as it's not used
anywhere else.

Root Complex Integrated Endpoints (RCiEPs) do not have an upstream bridge,
so pci_configure_mps() previously ignored them, which may result in reduced
performance.
Instead, program the Max_Payload_Size of RCiEPs to the maximum supported

affects the subsequent programming of Max_Read_Request_Size because Linux
programs MRRS based on the MPS value.

[ Upstream commit 3247bd10a4502a3075ce8e1c3c7d31ef76f193ce ]
All Intel platforms guarantee that all root complex implementations must
send transactions up to IOMMU for address translations. Hence for Intel
RCiEP devices, we can assume some ACS-type isolation even without an ACS
capability.
From the Intel VT-d spec, r3.1, sec 3.16 ("Root-Complex Peer to Peer
Considerations"):
When DMA remapping is enabled, peer-to-peer requests through the
Root-Complex must be handled as follows:
- The input address in the request is translated (through first-level,
second-level or nested translation) to a host physical address (HPA).
The address decoding for peer addresses must be done only on the
translated HPA. Hardware implementations are free to further limit
peer-to-peer accesses to specific host physical address regions (or
to completely disallow peer-forwarding of translated requests).
- Since address translation changes the contents (address field) of
the PCI Express Transaction Layer Packet (TLP), for PCI Express
peer-to-peer requests with ECRC, the Root-Complex hardware must use
the new ECRC (re-computed with the translated address) if it
decides to forward the TLP as a peer request.
- Root-ports, and multi-function root-complex integrated endpoints, may
support additional peer-to-peer control features by supporting PCI
Express Access Control Services (ACS) capability. Refer to ACS
capability in PCI Express specifications for details.
Since Linux didn't give special treatment to allow this exception, certain
RCiEP MFD devices were grouped in a single IOMMU group. This doesn't permit
a single device to be assigned to a guest for instance.
In one vendor system: Device 14.x were grouped in a single IOMMU group.
/sys/kernel/iommu_groups/5/devices/0000:00:14.0
/sys/kernel/iommu_groups/5/devices/0000:00:14.2
/sys/kernel/iommu_groups/5/devices/0000:00:14.3
After this patch:
/sys/kernel/iommu_groups/5/devices/0000:00:14.0
/sys/kernel/iommu_groups/5/devices/0000:00:14.2
/sys/kernel/iommu_groups/6/devices/0000:00:14.3 <<< new group
14.0 and 14.2 are integrated devices, but legacy end points, whereas 14.3
was a PCIe-compliant RCiEP.
00:14.3 Network controller: Intel Corporation Device 9df0 (rev 30)
Capabilities: [40] Express (v2) Root Complex Integrated Endpoint, MSI 00
This permits assigning this device to a guest VM.

On the ASUS laptop UX325JA/UX425JA, most of the media keys are not

as follows leads to the failure of asus_wmi_evaluate_method.

The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data

the size needs to be expanded to fix the problem.

The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist
Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.
Commit 1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".
And now we need to exten the whitelist again with 10 / "Notebook"...
The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.
So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.
Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.
