Merge tag 'platform-drivers-x86-v3.17-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86
Pull x86 platform drivers fixes from Darren Hart: "This is my first pull request since taking on maintenance for the platform-drivers-x86 tree from Matthew Garrett. These have passed my build testing and been run through Fengguang's LKP tests. Due to timing this round, these have not spent any time in linux-next. I have asked Stephen to include my for-next branch in linux-next going forward, once he's back from vacation. Details from tag: - toshiba_acpi: re-enable hotkeys and cleanups - ideapad-laptop: revert touchpad disable, and cleanup static/const usage - MAINTAINERS: update platform-drivers-x86 maintainer and tree" * tag 'platform-drivers-x86-v3.17-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86: toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store() platform/x86: toshiba: re-enable acpi hotkeys after suspend to disk ideapad-laptop: Constify DMI table for real!
