platform-drivers-x86 for v5.19-3 

Highlights:
  -  thinkpad_acpi/ideapad-laptop: mem-leak and platform-profile fixes
  -  panasonic-laptop: missing hotkey presses regression fix
  -  some hardware-id additions
  -  some other small fixes
 
 The following is an automated git shortlog grouped by driver:
 
 ACPI:
  -  video: Change how we determine if brightness key-presses are handled
 
 hp-wmi:
  -  Ignore Sanitization Mode event
 
 ideapad-laptop:
  -  Add Ideapad 5 15ITL05 to ideapad_dytc_v4_allow_table[]
  -  Add allow_v4_dytc module parameter
 
 intel/pmc:
  -  Add Alder Lake N support to PMC core driver
 
 panasonic-laptop:
  -  filter out duplicate volume up/down/mute keypresses
  -  don't report duplicate brightness key-presses
  -  revert "Resolve hotkey double trigger bug"
  -  sort includes alphabetically
  -  de-obfuscate button codes
 
 platform/mellanox:
  -  nvsw-sn2201: fix error code in nvsw_sn2201_create_static_devices()
 
 thinkpad_acpi:
  -  profile capabilities as integer
  -  do not use PSC mode on Intel platforms
  -  Fix a memory leak of EFCH MMIO resource
