Merge tag 'platform-drivers-x86-v4.13-1' of git://git.infradead.org/linux-platform-drivers-x86
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 eeepc-laptop: - constify platform_attribute_group toshiba_haps: - constify haps_attr_group dell-wmi-led: - Adjust instance of wmi_evaluate_method calls to 0 alienware-wmi: - Adjust instance of wmi_evaluate_method calls to 0 intel_menlow: - Add const to thermal_cooling_device_ops structure acerhdf: - Add const to thermal_cooling_device_ops structure dell-laptop: - Fix bogus keyboard backlight sysfs interface acer-wmi: - Using zero as first WMI instance number - Detect RF Button capability ideapad-laptop: - Add Y720-15IKBN to no_hw_rfkill - 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 topstar-laptop: - Add new device id peaq-wmi: - Add new peaq-wmi driver thinkpad_acpi: - Add a comment about 0 in module_param_call() - Join string literals back toshiba_acpi: - use memdup_user_nul" * tag 'platform-drivers-x86-v4.13-1' of git://git.infradead.org/linux-platform-drivers-x86: (67 commits) platform/x86: sony-laptop: constify attribute_group and input index array platform/x86: fujitsu-laptop: rework debugging platform/x86: fujitsu-laptop: do not evaluate ACPI _INI methods platform/x86: fujitsu-laptop: do not update ACPI device power status platform/x86: fujitsu-laptop: sanitize hotkey input device identification platform/x86: fujitsu-laptop: use strcpy to set ACPI device names and classes platform/x86: fujitsu-laptop: remove redundant safety checks platform/x86: msi-laptop: constify msipf*_attribute_group platform/x86: eeepc-laptop: constify platform_attribute_group platform/x86: toshiba_haps: constify haps_attr_group platform/x86: dell-wmi-led: Adjust instance of wmi_evaluate_method calls to 0 platform/x86: alienware-wmi: Adjust instance of wmi_evaluate_method calls to 0 platform/x86: intel_menlow: Add const to thermal_cooling_device_ops structure platform/x86: acerhdf: Add const to thermal_cooling_device_ops structure platform/x86: dell-laptop: Fix bogus keyboard backlight sysfs interface platform/x86: acer-wmi: Using zero as first WMI instance number platform/x86: ideapad-laptop: Add Y720-15IKBN to no_hw_rfkill platform/x86: ideapad-laptop: Add Y520-15IKBN to no_hw_rfkill platform/x86: silead_dmi: Add touchscreen info for PoV mobii wintab p800w platform/x86: silead_dmi: Add touchscreen info for Pipo W2S tablet ...
