Pull x8 platform driver updates from Darren Hart:
 "Several new quirks and tweaks for new platforms to existing laptop
  drivers.  A new ACPI virtual power button driver, similar to the
  intel-hid driver.  A rework of the dell keymap, using a single sparse
  keymap for all machines.  A few fixes and cleanups.

  Summary:

  intel-vbtn:
   - new driver for Intel Virtual Button

  intel_pmc_core:
   - Convert to DEFINE_DEBUGFS_ATTRIBUTE

  fujitsu-laptop:
   - Rework brightness of eco led

  asus-wmi:
   - Add quirk_no_rfkill_wapf4 for the Asus X456UA
   - Add quirk_no_rfkill_wapf4 for the Asus X456UF
   - Add quirk_no_rfkill for the Asus Z550MA
   - Add quirk_no_rfkill for the Asus U303LB
   - Add quirk_no_rfkill for the Asus N552VW
   - Create quirk for airplane_mode LED
   - Add ambient light sensor toggle key

  asus-wireless:
   - Toggle airplane mode LED

  intel_telemetry:
   - Remove Monitor MWAIT feature dependency

  intel-hid:
   - Remove duplicated acpi_remove_notify_handler

  fujitsu-laptop:
   - Add support for eco LED
   - Support touchpad toggle hotkey on Skylake-based models
   - Remove unused macros
   - Use module name in debug messages

  hp-wmi:
   - Fix wifi cannot be hard-unblocked

  toshiba_acpi:
   - Bump driver version and update copyright year
   - Remove the position sysfs entry
   - Add IIO interface for accelerometer axis data

  dell-wmi:
   - Add a WMI event code for display on/off
   - Generate one sparse keymap for all machines
   - Add information about other WMI event codes
   - Sort WMI event codes and update comments
   - Ignore WMI event code 0xe045"
