Pull x86 platform driver updates from Darren Hart:
 "Introduce new bus architecture for WMI and expose BMOF data through
  sysfs. Correct several assumptions about WMI instance number from 1 to
  0. Further fujitsu-laptop cleanups, continuing to prepare for
  separation into two modules. Add support for several new ideapad
  laptops and silead-based tablets. Various minor fixes and const
  cleanups.

  Detail summary:

  sony-laptop:
   - constify attribute_group and input index array

  fujitsu-laptop:
   - rework debugging
   - do not evaluate ACPI _INI methods
   - do not update ACPI device power status
   - sanitize hotkey input device identification
   - use strcpy to set ACPI device names and classes
   - remove redundant safety checks
   - use device-specific data in remaining module code
   - use device-specific data in LED-related code
   - explicitly pass ACPI device to call_fext_func()
   - track the last instantiated FUJ02E3 ACPI device
   - allocate fujitsu_laptop in acpi_fujitsu_laptop_add()
   - use device-specific data in backlight code
   - allocate fujitsu_bl in acpi_fujitsu_bl_add()
   - distinguish current uses of device-specific data

  msi-laptop:
   - constify msipf*_attribute_group

   - Add Y520-15IKBN to no_hw_rfkill
   - constify rfkill_ops structure
   - Squelch ACPI event 1
   - hide unused 'touchpad_store'
   - Switch touchpad attribute to be RO
   - Add sysfs interface for touchpad state

  silead_dmi:
   - Add touchscreen info for PoV mobii wintab p800w
   - Add touchscreen info for Pipo W2S tablet
   - Add touchscreen info for GP-electronic T701

  dell-rbtn:
   - constify rfkill_ops structures
   - Improve explanation about DELLABC6

  samsung-laptop:
   - constify rfkill_ops structures

  panasonic-laptop:
   - remove unused code

  samsung-laptop:
   - Initialize loca variable

  dell-wmi:
   - Convert to the WMI bus infrastructure
   - Add a better description for "stealth mode"
   - Add a comment explaining the 0xb2 magic number

  wmi-bmof:
   - New driver to expose embedded Binary WMI MOF metadata

  wmi*:
   - Fix printing info about WDG structure
   - Add recent copyright statements
   - Require query for data blocks, rename writable to setable
   - Add an interface for subdrivers to access sibling devices
   - Bind the platform device, not the ACPI node
   - Add a new interface to read block data
   - Incorporate acpi_install_notify_handler
   - Instantiate all devices before adding them
   - Probe data objects for read and write capabilities
   - Split devices into types and add basic sysfs attributes
   - Fix error handling when creating devices
   - Turn WMI into a bus driver
   - Track wmi devices per ACPI device
   - Clean up acpi_wmi_add
   - Pass the acpi_device through to parse_wdg
   - Drop "Mapper (un)loaded" messages

  intel_cht_int33fe:
   - Set supplied-from property on max17047 dev

  intel_pmc_ipc:
   - Mark ipc_data_readb() as __maybe_unused
