Pull x86 platform driver updates from Andy Shevchenko:
 "Gathered a bunch of x86 platform driver changes. It's rather big,
  since includes two big refactors and completely new driver:

   - ASUS WMI driver got a big refactoring in order to support the TUF
     Gaming laptops. Besides that, the regression with backlight being
     permanently off on various EeePC laptops has been fixed.

   - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
     X axis being inverted. This has been fixed.

   - Intel PMC core driver has been extended to be ACPI enumerated if
     the DSDT provides device with _HID "INT33A1". This allows to
     convert the driver to be pure platform and support new hardware
     purely based on ACPI DSDT.

   - From now on the Intel Speed Select Technology is supported thru a
     corresponding driver. This driver provides an access to the
     features of the ISST, such as Performance Profile, Core Power, Base
     frequency and Turbo Frequency.

   - Mellanox platform drivers has been refactored and now extended to
     support more systems, including new coming ones.

   - The OLPC XO-1.75 platform is now supported.

   - CB4063 Beckhoff Automation board is using PMC clocks, provided via
     pmc_atom driver, for ethernet controllers in a way that they can't
     be managed by the clock driver. The quirk has been extended to
     cover this case.

   - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
     the information of Chuwi Hi10 Air has been fixed to cover more
     models based on the same platform.

   - Xiaomi notebooks have WMI interface enabled. Thus, the driver to
     support it has been provided. It required some extension of the
     generic WMI library, which allows to propagate opaque context to
     the ->probe() of the individual drivers.

  This release includes debugfs clean up from Greg KH for several
  drivers that drop return code check and make debugfs absence or
  failure non-fatal.

  Also miscellaneous fixes here and there, mostly for Acer WMI and
  various Intel drivers"
