Pull char/misc driver fixes from Greg KH:
 "Here are some small char/misc and other subsystem driver fixes for
  6.2-rc5 to resolve a few reported issues. They include:

   - long time pending fastrpc fixes (should have gone into 6.1, my
     fault)

   - mei driver/bus fixes and new device ids

   - interconnect driver fixes for reported problems

   - vmci bugfix

   - w1 driver bugfixes for reported problems

  Almost all of these have been in linux-next with no reported problems,
  the rest have all passed 0-day bot testing in my tree and on the
  mailing lists where they have sat too long due to me taking a long
  time to catch up on my pending patch queue"

Pull ARM SoC DT and driver fixes from Arnd Bergmann:
 "Lots of dts fixes for Qualcomm Snapdragon and NXP i.MX platforms,
  including:

   - A regression fix for SDHCI controllers on Inforce 6540, and another
     SDHCI fix on SM8350

   - Reenable cluster idle on sm8250 after the the code fix is upstream

   - multiple fixes for the QMP PHY binding, needing an incompatible dt
     change

   - The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus
     6P, to avoid instabilities caused by use of protected memory
     regions

   - Fix i.MX8MP DT for missing GPC Interrupt, power-domain typo and USB
     clock error

   - A couple of verdin-imx8mm DT fixes for audio playback support

   - Fix pca9547 i2c-mux node name for i.MX and Vybrid device trees

   - Fix an imx93-11x11-evk uSDHC pad setting problem that causes Micron
     eMMC CMD8 CRC error in HS400ES/HS400 mode

  The remaining ARM and RISC-V platforms only have very few smaller dts
  bugfixes this time:

   - A fix for the SiFive unmatched board's PCI memory space

   - A revert to fix a regression with GPIO on Marvell Armada

   - A fix for the UART address on Marvell AC5

   - Missing chip-select phandles for stm32 boards

   - Selecting the correct clock for the sam9x60 memory controller

   - Amlogic based Odroid-HC4 needs a revert to restore USB
     functionality.

  And finally, there are some minor code fixes:

   - Build fixes for OMAP1, pxa, riscpc, raspberry pi firmware, and zynq
     firmware

   - memory controller driver fixes for an OMAP regression and older
     bugs on tegra, atmel and mvebu

   - reset controller fixes for ti-sci and uniphier platforms

   - ARM SCMI firmware fixes for a couple of rare corner cases

   - Qualcomm platform driver fixes for incorrect error handling and a
     backwards compatibility fix for the apr driver using older dtb

   - NXP i.MX SoC driver fixes for HDMI output, error handling in the
     imx8 soc-id and missing reference counting on older cpuid code"

We can get EFI variables without fetching the attribute, so we must
allow for that in gsmi.

commit 859748255b43 ("efi: pstore: Omit efivars caching EFI varstore
access layer") added a new get_variable call with attr=NULL, which
triggers panic in gsmi.

Pull kernel hardening fixes from Kees Cook:

 - Fix CFI hash randomization with KASAN (Sami Tolvanen)

 - Check size of coreboot table entry and use flex-array

* tag 'hardening-v6.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
  kbuild: Fix CFI hash randomization with KASAN
  firmware: coreboot: Check size of table entry and use flex-array

The memcpy() of the data following a coreboot_table_entry couldn't
be evaluated by the compiler under CONFIG_FORTIFY_SOURCE. To make it
easier to reason about, add an explicit flexible array member to struct
coreboot_device so the entire entry can be copied at once. Additionally,
validate the sizes before copying. Avoids this run-time false positive
warning:

  memcpy: detected field-spanning write (size 168) of single field "&device->entry" at drivers/firmware/google/coreboot_table.c:103 (size 8)

Contrary to popular belief, PSCI is not a universal property of an
ARM/arm64 system. There is a garden variety of systems out there
that don't (or even cannot) implement it.

I'm the first one deplore such a situation, but hey...

On such systems, a "cat /sys/kernel/debug/psci" results in
fireworks, as no invocation callback is registered.

Check for the invoke_psci_fn and psci_ops.get_version pointers
before registering with the debugfs subsystem, avoiding the
issue altogether.
