Merge tag 'platform-drivers-x86-v3.18-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86
Pull x86 platform driver updates from Darren Hart: "The following have all spent at least a few days in linux-next, most for more than a week. These are mostly cleanups and error handling improvements with a few updates to extend existing support to newer hardware. Details: - dell-wmi: fix access out of memory - eeepc-laptop: cleanups, refactoring, sysfs perms, and improved error handling - intel-rst: ACPI and error handling cleanups - thinkpad-acpi: whitespace cleanup - toshiba_acpi: HCI/SCI interface update, keyboard backlight type 2 support, new scancodes, cleanups" * tag 'platform-drivers-x86-v3.18-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86: (23 commits) toshiba_acpi: Adapt kbd_bl_timeout_store to the new kbd type toshiba_acpi: Change HCI/SCI functions return code type toshiba_acpi: Unify return codes prefix from HCI/SCI to TOS toshiba_acpi: Rename hci_raw to tci_raw dell-wmi: Fix access out of memory eeepc-laptop: clean up control flow in *_rfkill_notifier eeepc-laptop: store_cpufv: return error if set_acpi fails eeepc-laptop: check proper return values in get_cpufv eeepc-laptop: make fan1_input really read-only eeepc-laptop: pull out SENSOR_STORE_FUNC and SENSOR_SHOW_FUNC macros eeepc-laptop: tell sysfs that the disp attribute is write-only eeepc-laptop: pull out ACPI_STORE_FUNC and ACPI_SHOW_FUNC macros eeepc-laptop: use DEVICE_ATTR* to instantiate device_attributes eeepc-laptop: change sysfs function names to API expectations eeepc-laptop: clean up coding style eeepc-laptop: simplify parse_arg() intel-rst: Clean up ACPI add function intel-rst: Use ACPI_FAILURE() macro instead !ACPI_SUCCESS() for error checking x86: thinkpad_acpi.c: fixed spacing coding style issue toshiba_acpi: Support new keyboard backlight type ...
