platform-drivers-x86 for 4.6-1

Browse source 
Significant refactoring of Dell laptop drivers, modularizing the smbios code.
 Multiple new platforms added for ideapad, asus, dell, and alienware using
 existing quirks. A few fixes and cleanups.
 
 hp-wmi:
  - Remove GPS rfkill support via pre-2009 interface
  - fix unregister order in hp_wmi_rfkill_setup() once again
 
 ideapad-laptop:
  - Add ideapad Y700 (15) to the no_hw_rfkill DMI list
 
 fujitsu-laptop:
  - Support radio toggle button
 
 intel-hid:
  - allocate correct amount of memory for private struct
 
 platform/x86:
  - Make intel_scu_ipc explicitly non-modular
 
 intel_pmc_ipc:
  - Avoid pending IPC1 command during legacy suspend
  - Fix GCR register base address and length
 
 asus-nb-wmi:
  - add wapf=4 quirk for ASUS X75VD
 
 intel_telemetry_pltdrv:
  - Change verbosity control bits
 
 dell-rbtn:
  - Add a comment about the XPS 13 9350
 
 dell-wmi, dell-laptop:
  - depends DMI
 
 dell-wmi:
  - support Dell Inspiron M5110
  - properly process Dell Instant Launch hotkey
  - enable receiving WMI events on Dell Vostro V131
  - Support new hotkeys on the XPS 13 9350 (Skylake)
  - Clean up hotkey table size check
  - Stop storing pointers to DMI tables
 
 dell-laptop:
  - move dell_smi_error() to dell-smbios
  - use dell_smbios_find_token() instead of find_token_location()
  - use dell_smbios_find_token() instead of find_token_id()
  - extract SMBIOS-related code to a separate module
 
 dell-smbios:
  - rename dell_smi_error() to dell_smbios_error()
  - make da_tokens static
  - remove find_token_{id,location}()
  - implement new function for finding DMI table 0xDA tokens
  - make the SMBIOS buffer static
  - return the SMBIOS buffer from dell_smbios_get_buffer()
  - don't return an SMBIOS buffer from dell_smbios_send_request()
  - don't pass an SMBIOS buffer to dell_smbios_send_request()
  - rename dell_send_request() to dell_smbios_send_request()
  - rename release_buffer() to dell_smbios_release_buffer()
  - rename clear_buffer() to dell_smbios_clear_buffer()
  - rename get_buffer() to dell_smbios_get_buffer()
 
 dell-led:
  - use dell_smbios_send_request() for performing SMBIOS calls
  - use dell_smbios_find_token() for finding mic DMI tokens
 
 toshiba_acpi:
  - Add a module parameter to disable hotkeys registration
  - Add sysfs entries for the Cooling Method feature
  - Add support for cooling method feature
 
 Documentation/ABI:
