[ Upstream commit a9f07790a4b2250f0140e9a61c7f842fd9b618c7 ]
This function may copy the pad0 field of struct hl_info_sec_attest to user
mode which has not been initialized, resulting in leakage of kernel heap
data to user mode. To prevent this, use kzalloc() to allocate and zero out
the buffer, which can also eliminate other uninitialized holes, if any.

[ Upstream commit c8048dd0b07df68724805254b9e994d99e9a7af4 ]
The mtk_dp driver registers a phy device which is handled by the
phy_mtk_dp driver and assumes that the phy probe will complete
synchronously, proceeding to make use of functionality exposed by that
driver right away. This assumption however is false when the phy driver
is built as a module, causing the mtk_dp driver to fail probe in this
case.
Add the phy_mtk_dp module as a pre-dependency to the mtk_dp module to
ensure the phy module has been loaded before the dp, so that the phy
probe happens synchrounously and the mtk_dp driver can probe
successfully even with the phy driver built as a module.

[ Upstream commit ddd1ee12a8fb6e4d6f86eddeba64c135eee56623 ]
The Vangogh machine driver variant based on the MAX98388 amplifier, as
found on Valve's Steam Deck OLED, relies on probing via an ACPI match
table. This worked fine until commit 197b1f7f0df1 ("ASoC: amd: Add new
dmi entries to config entry") enabled SOF support for the target machine
(i.e. Galileo product), causing the sound card to enter the deferred
probe state indefinitely:
$ cat /sys/kernel/debug/devices_deferred
AMDI8821:00 acp5x_mach: Register card (acp5x-max98388) failed
The issue is related to commit e89f45edb747 ("ASoC: amd: vangogh: Add
check for acp config flags in vangogh platform"), which tries to
mitigate potential conflicts between SOF and generic ACP Vangogh
drivers, due to sharing the PCI device IDs.
However, the solution is effective only if the machine driver is
directly probed by pci-acp5x through platform_device_register_full().
Hence, remove the conflicting ACPI based probing and rely exclusively on
DMI quirks for sound card setup.

Avoid unnecessary crashes by claiming only NMIs that are due to
ERROR signalling or generated by the hpwdt hardware device.
The code does this, but only for iLO5.
The intent was to preserve legacy, Gen9 and earlier, semantics of
using hpwdt for error containtment as hardware/firmware would signal
fatal IO errors as an NMI with the expectation of hpwdt crashing
the system. Howerver, these IO errors should be received by hpwdt
as an NMI_IO_CHECK. So the test is overly permissive and should
not be limited to only ilo5.
We need to enable this protection for future iLOs not matching the
current PCI IDs.

[ Upstream commit 38d75297745f04206db9c29bdd75557f0344c7cc ]
When the new watchdog character device is registered, it becomes
available for opening. This creates a race where userspace may open the
device before the character device's owner is set. This results in an
imbalance in module_get calls as the cdev_get in cdev_open will not
increment the reference count on the watchdog driver module.
This causes problems when the watchdog character device is released as
the module loader's reference will also be released. This makes it
impossible to open the watchdog device later on as it now appears that
the module is being unloaded. The open will fail with -ENXIO from
chrdev_open.
The legacy watchdog device will fail with -EBUSY from the try_module_get
in watchdog_open because it's module owner is the watchdog core module
so it can still be opened but it will fail to get a refcount on the
underlying watchdog device driver.

Currently zynqmp clock driver is not calculating closest mux rate and
because of that Linux is not setting proper frequency for CPU and
not able to set given frequency for dynamic frequency scaling.
E.g., In current logic initial acpu clock parent and frequency as below
apll1 0 0 0 2199999978 0 0 50000 Y
acpu0_mux 0 0 0 2199999978 0 0 50000 Y
acpu0_idiv1 0 0 0 2199999978 0 0 50000 Y
acpu0 0 0 0 2199999978 0 0 50000 Y
After changing acpu frequency to 549999994 Hz using CPU freq scaling its
selecting incorrect parent which is not closest frequency.
rpll_to_xpd 0 0 0 1599999984 0 0 50000 Y
acpu0_mux 0 0 0 1599999984 0 0 50000 Y
acpu0_div1 0 0 0 533333328 0 0 50000 Y
acpu0 0 0 0 533333328 0 0 50000 Y
Parent should remain same since 549999994 = 2199999978 / 4.
So use __clk_mux_determine_rate_closest() generic function to calculate
closest rate for mux clock. After this change its selecting correct
parent and correct clock rate.

Code in rzg2l_cpg_reset() is equivalent with the combined code of
rzg2l_cpg_assert() and rzg2l_cpg_deassert(). There is no need to have
different versions thus re-use rzg2l_cpg_assert() and rzg2l_cpg_deassert().

The AVCL register, according to the datasheet, comes in increments
of -0.2v between -4.4v (represented by 0x0) to -5.0v (represented
by 0x3). The current calculation is done by adding the defined
AVCL value in mV to -4400 and then dividing by 200 to get the register
value. Unfortunately if I subtract -4400 from -4400 I get -8800, which
divided by 200 gives me -44. If I instead subtract -4400 from -4400
I get 0, which divided by 200 gives me 0. Based on the datasheet this
is the expected register value.

The driver always enables the clocks at probe() and disables them only
at remove(). It is not clear why the driver does this, as it supports
runtime PM, and enables and disables the clocks in the runtime resume
and suspend callbacks. Also, in the case runtime PM is not available,
the driver calls the resume and suspend callbacks manually from probe()
and remove().
Drop the unnecessary clock enable, thus enabling the clocks only when
actually needed.

mipi_csis_clk_disable() in a way that reverses what is done in probe().

[ Upstream commit 3f1faa154a4316b1b585a25394697504b3c24e98 ]
The old (now removed) videobuf framework had an optional vbi hack where
the sequence number of the frame counter was copied in the last 4 bytes
of the buffer. This hack was active only for the read() interface
(so not for streaming I/O), and it was enabled by bttv. This allowed
applications that used read() for the VBI data to match it with the
corresponding video frame.
When bttv was converted to vb2 this hack was forgotten, but some old
applications rely on this.
So add this back, but this time in the bttv driver rather than in the
vb2 framework.
