platform-drivers-x86 for v4.12-1
This pull requests represents a significantly larger and more complex set of changes than those of prior merge windows. In particular, we had several changes with dependencies on other subsystems which we felt were best managed through merges of immutable branches, including one each from input, i2c, and leds. Two patches for the watchdog subsystem are included after discussion with Wim and Guenter following a collision in linux-next (this should be resolved and you should only see these two appear in this pull request). These are called out in the "External" section below. Summary of changes: - significant further cleanup of fujitsu-laptop and hp-wmi - new model support for ideapad, asus, silead, and xiaomi - new hotkeys for thinkpad and models using intel-vbtn - dell keyboard backlight improvements - build and dependency improvements - intel * ipc fixes, cleanups, and api updates - single isolated fixes noted below External: - watchdog: iTCO_wdt: Add PMC specific noreboot update api - watchdog: iTCO_wdt: cleanup set/unset no_reboot_bit functions -
