Pull x86 platform driver fixes from

 - Add ACPI_HANDLE()/ACPI_COMPANION() NULL checks (many drivers) to
   handle match overrides gracefully

 - asus-armoury:
    - Fix mini-LED mode get/set
    - Add support for FA401EA, FX607VU, G614FR, and GU605CP

 - bitland-mifs-wmi:
    - Add CONFIG_LEDS_CLASS dependency

 - hp-wmi:
    - Add thermal support for Omen 16-c0xxx (board 8902)

 - intel/vsec:
    - Fix enable_cnt imbalance due to PCIe error recovery

 - surface/aggregator_registry:
    - Remove battery & AC nodes on Surface Laptop 7 to avoid duplicated
      devices

 - uniwill-laptop:
    - Handle uninitialized and invalid charging threshold values
    - Accept charging threshold of 0 through power supply sysfs ABI and
      clamp it to 1
    - Make 'force' parameter to work also when device descriptor is
      found
    - Do not enable charging limit despite the 'force' parameter to
      avoid permanent damage to battery
