Pull SoC driver updates from Arnd Bergmann:
"The SoC driver changes once more consist of many small fixes and
cleanups, that are to a large part the result of automated testing.
On platform specific drivers, this includes SoC specific code for
xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung,
rockchip, renesas, ixp4xx. In firmware drivers, we see a similar
picture for SCMI and qcomtee.
Aside from these, we see actual new hardware support in a few areas:
- The Apple platform gets a new driver for low power states
- Updates to Qualcomm platform drivers add several new hardware
specific features and additional SoCs.
- Amlogic SoC support for A1 and T7 is added
- The Mediatek MMSYS driver is refactored as a cleanup"

Sashiko (locally) reports a possible null dereference under memory
pressure due to the lack of validation of the allocated pointer.
Fix that by adding the missing check.

The driver explicitly sets the .driver_data member of struct platform_device_id to zero without relying on that value. Drop this unused assignment. While touching this array unify spacing and usage of commas and use a named initializer for .name for improved readability.

Pull SoC driver updates from Arnd Bergmann:
"There are a few added drivers, but mostly the normal maintenance to
drivers for firmware, memory controller and other soc specific
hardware:
- The NXP QuickEngine gets modern MSI support, which allows some
cleanups to the GICv3 irqchip chip driver
- A new SoC specific driver for the Renesas R-Car MFIS unit is added,
encapsulating support for the on-chip mailbox and hwspinlock
implementations that are not easily separated into individual
drivers
- The Qualcomm SoC drivers add support for additional SoC
implementations, and flexibility around power management for the
serial-engine driver as well as probing the LLCC driver using
custom hardware descriptions inside of the device itself.
- Added support for the Samsung thermal management unit
- A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
APIs and allow multiple PMC instances everywhere.
- Updates to the TI SCI and KNAS drivers to improve suspend/resume
support.
- Minor driver changes for mediatek, xilinx, allwinner, aspeed,
tegra, broadcom, amd, microchip and starfive specific drivers
- Memory controller updates for Tegra and Renesas for additional SoC
types and other improvements.
- Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces, to
update driver probing, object lifetimes and address minor bugs"

qcomtee_object_user_init() is a variadic function and when the function
return because there's no dispatch callback in QCOMTEE_OBJECT_TYPE_CB
case, there's no va_end to cleanup "ap" object initialized by va_start
and that can cause undefined behavior. So make sure to use va_end before
returning the error code when there's no dispatch callback.
This is reported by Coverity Scan as "Missing varargs init or cleanup".
