Pull x86 platform driver updates from Andy Shevchenko:

 - The driver for Silead touchscreen configurations has been renamed
   from silead_dmi to touchscreen_dmi since it starts supporting other
   touchscreens which require some DMI quirks

   It also gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
   Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.

 - Another bunch of changes is related to Mellanox platform code to
   allow user space to communicate with Mellanox for system control and
   monitoring purposes. The driver notifies user on hotplug device
   signal receiving.

 - ASUS WMI drivers recognize lid flip action on UX360, and correctly
   toggles airplane mode LED. In addition the keyboard backlight toggle
   gets support.

 - ThinkPad ACPI driver enables support for calculator key (on at least
   P52). It also has been fixed to support three characters model
   designators, which are used for modern laptops. Earlier the battery,
   marked as BAT1, on ThinkPad laptops has not been configured properly,
   which is fixed. On the opposite the multi-battery configurations now
   probed correctly.

 - Dell SMBIOS driver starts working on some Dell servers which do not
   support token interface. The regression with backlight detection has
   also been fixed. In order to support dock mode on some laptops, Intel
   virtual button driver has been fixed. The last but not least is the
   fix to Intel HID driver due to changes in Dell systems that prevented
   to use power button.
