Browse Source 
Highlights:
  -  Surface Pro 9 and Surface Laptop 5 kbd, battery, etc. support
     (this is just a few hw-id additions)
  -  A couple of other hw-id / DMI-quirk additions
  -  A few small bug fixes + 1 build fix
 
 The following is an automated git shortlog grouped by driver:
 
 acer-wmi:
  -  Enable SW_TABLET_MODE on Switch V 10 (SW5-017)
 
 asus-wmi:
  -  add missing pci_dev_put() in asus_wmi_set_xusb2pr()
 
 hp-wmi:
  -  Ignore Smart Experience App event
 
 ideapad-laptop:
  -  Add module parameters to match DMI quirk tables
  -  Fix interrupt storm on fn-lock toggle on some Yoga laptops
 
 platform/surface:
  -  aggregator_registry: Add support for Surface Laptop 5
  -  aggregator_registry: Add support for Surface Pro 9
  -  aggregator: Do not check for repeated unsequenced packets
 
 platform/x86/amd:
  -  pmc: Add new ACPI ID AMDI0009
  -  pmc: Remove more CONFIG_DEBUG_FS checks
 
 platform/x86/intel:
  -  pmc: Don't unconditionally attach Intel PMC when virtualized
 
 thinkpad_acpi:
  -  Enable s2idle quirk for 21A1 machine type
