Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86

Browse Source 
Pull x86 platform drivers update from Matthew Garrett:
 "Nothing amazingly special here.  Some cleanups, a new driver to
  support a single button on some new HPs, a tiny amount of hardware
  enablement"

* 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86:
  ipc: add intel-mid's pci id macros
  hp-wireless: new driver for hp wireless button for Windows 8
  toshiba_acpi: Support RFKILL hotkey scancode
  hp_accel: Add a new PnP ID HPQ6007 for new HP laptops
  sony-laptop: remove unnecessary assigment of len
  fujitsu-laptop: fix error return code
  dell-laptop: Only install the i8042 filter when rfkill is active
  X86 platform: New BayTrail IOSF-SB MBI driver
  drivers: platform: Include appropriate header file in mxm-wmi.c
  drivers: platform: Mark functions as static in hp_accel.c
  dell-laptop: rkill whitelist Precision models
  ipc: simplify platform data approach
  asus-wmi: Convert to use devm_hwmon_device_register_with_groups
  compal-laptop: Use devm_hwmon_device_register_with_groups
  compal-laptop: Replace SENSOR_DEVICE_ATTR with DEVICE_ATTR
  eeepc-laptop: Convert to use devm_hwmon_device_register_with_groups
  compal-laptop: Use devm_kzalloc to allocate local data structure
  dell-laptop: fix to return error code in dell_send_intensity()
