Merge tag 'platform-drivers-x86-v5.3-2' of git://git.infradead.org/linux-platform-drivers-x86 

Pull another x86 platform driver update from Andy Shevchenko:
 "Provide better naming for ABI, i.e. tell that we have fan boost mode.

  It won't break any ABI, but has to be done now to avoid confusion in
  the future"

* tag 'platform-drivers-x86-v5.3-2' of git://git.infradead.org/linux-platform-drivers-x86:
  platform/x86: asus: Rename "fan mode" to "fan boost mode"
