Subject: [GIT PULL] ACPI fixes for v6.18-rc4

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-6.18-rc4

with top-most commit 8907226bed1ebd10d069f6f70ff0aaa8840f3267

 Merge branches 'acpi-button', 'acpi-video' and 'acpi-fan'

on top of commit dcb6fa37fd7bc9c3d2b066329b0d27dedf8becaa

 Linux 6.18-rc3

to receive ACPI fixes for 6.18-rc4.

These fix three ACPI driver issues and add version checks to two ACPI
table parsers:

 - Call input_free_device() on failing input device registration as
   necessary (and mentioned in the input subsystem documentation) in the
   ACPI button driver (Kaushlendra Kumar)

 - Fix use-after-free in acpi_video_switch_brightness() by canceling
   a delayed work during tear-down (Yuhao Jiang)

 - Use platform device for devres-related actions in the ACPI fan driver
   to allow device-managed resources to be cleaned up properly (Armin
   Wolf)

 - Add version checks to the MRRM and SPCR table paresers (Tony Luck and
   Punit Agrawal)

Thanks!
