Merge tag 'platform-drivers-x86-v4.2-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86
Pull x86 platform driver updates from Darren Hart: "Fairly routine update for platform-drivers-x86. Mostly fixes and cleanups, with a significant refactoring of toshiba* drivers. Includes the addition of the dell-rbtn driver. Details: asus-wmi: - fan control dell*: - add Dell airplane mode switch driver ideapad-laptop: - platform rfkill fixes, and regression fix pvpanic: - handle missing _STA correctly toshiba*: - rafactor bluetooth support - haps documentation - driver cleanup other: - Use acpi_video_unregister_backlight instead of acpi_video_unregister in serveral drivers. - Orphan msi-wmi. * tag 'platform-drivers-x86-v4.2-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86: (24 commits) MAINTAINERS: Orphan x86 driver msi-wmi ideapad: fix software rfkill setting dell-laptop: Use dell-rbtn instead i8042 filter when possible dell-rbtn: Export notifier for other kernel modules dell-rbtn: Dell Airplane Mode Switch driver samsung-laptop: Use acpi_video_unregister_backlight instead of acpi_video_unregister asus-wmi: Use acpi_video_unregister_backlight instead of acpi_video_unregister apple_gmux: Use acpi_video_unregister_backlight instead of acpi_video_unregister pvpanic: handle missing _STA correctly ideapad_laptop: Lenovo G50-30 fix rfkill reports wireless blocked asus-wmi: add fan control Documentation/ABI: Add file describing the sysfs entries for toshiba_haps toshiba_haps: Make use of DEVICE_ATTR_{RW, WO} macros toshiba_haps: Replace sscanf with kstrtoint toshiba_acpi: Bump driver version to 0.22 toshiba_acpi: Remove TOS_FAILURE check from some functions toshiba_acpi: Comments cleanup toshiba_acpi: Rename hci_{read, write}1 functions toshiba_acpi: Remove no longer needed hci_{read, write}2 functions toshiba_bluetooth: Change BT status message to debug ...
