Merge tag 'platform-drivers-x86-v3.20-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86
Pull platform driver update from Darren Hart: "This includes a significant update to the toshiba_acpi driver, bringing it to feature parity with the Windows driver, followed by some needed cleanups. The other changes are mostly minor updates, quirks, sparse fixes, or cleanups. Details: - toshiba_acpi: Add support for missing features from the Windows driver, bump the sysfs version, and clean up the driver. - thinkpad_acpi: BIOS string versions, unhandled hkey events. - msamsung-laptop: Add native backlight quirk, enable better lid handling. - intel_scu_ipc: Read resources from PCI configuration - other: Fix sparse warnings, general cleanups" * tag 'platform-drivers-x86-v3.20-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86: (34 commits) toshiba_acpi: Cleanup GPL header toshiba_acpi: Cleanup comment blocks and capitalization toshiba_acpi: Make use of DEVICE_ATTR_{RO, RW} macros toshiba_acpi: Drop the toshiba_ prefix from sysfs function names toshiba_acpi: Move sysfs function and struct declarations further down Documentation/ABI: Add file describing the sysfs entries for toshiba_acpi toshiba_acpi: Clean file according to coding style toshiba_acpi: Bump version number to 0.21 toshiba_acpi: Add support to enable/disable USB 3 toshiba_acpi: Add support for Panel Power ON toshiba_acpi: Add support for Keyboard functions mode toshiba_acpi: Add fan entry to sysfs toshiba_acpi: Add version entry to sysfs thinkpad_acpi: support new BIOS version string pattern thinkpad_acpi: unhandled hkey event toshiba_acpi: Make toshiba_eco_mode_available more robust classmate-laptop: Fix sparse warning (0 as NULL) Sony-laptop: Fix sparse warning (make undeclared var static) thinkpad_acpi.c: Fix sparse warning (make undeclared var static) samsung-laptop.c: Prefer kstrtoint over single variable sscanf ...
