Pull x86 platform driver revert from Matthew Garrett: "It turns out that one of the hp-wmi patches this cycle breaks some other HP laptops. I think we have a good idea how to work on it for 3.10, but it's safer to just revert it for now." * 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86: Revert "hp-wmi: Add support for SMBus hotkeys"

Revert "hp-wmi: Add support for SMBus hotkeys"

2013-04-18T21:53:10Z

This reverts commit fabf85e3ca15d5b94058f391dac8df870cdd427a which breaks hotkey support on some other HP laptops. We'll try doing this differently in 3.10. Signed-off-by: Matthew Garrett

thinkpad-acpi: kill hotkey_thread_mutex

2013-04-17T23:10:44Z

hotkey_kthread() does try_to_freeze() under hotkey_thread_mutex. We can simply kill this mutex, hotkey_poll_stop_sync() does not need to serialize with hotkey_kthread(). When kthread_stop() returns the thread is already dead, it called do_exit()->complete_vfork_done().

ideapad-laptop: Depend on BACKLIGHT_CLASS_DEVICE instead of selecting it

2013-02-27T13:30:47Z

Selecting BACKLIGHT_CLASS_DEVICE doesn't guarantee that any of its dependencies are enabled, and these are complicated. Depending isn't ideal for configuration UI purposes, but is probably more appropriate here. Signed-off-by: Matthew Garrett

ideapad: depends on backlight subsystem and update comment

I've got a report of build failure on ideapad-laptop, which shows drivers/built-in.o: In function `ideapad_acpi_notify': ideapad-laptop.c:(.text+0x63876a): undefined reference to `backlight_force_update' drivers/built-in.o: In function `ideapad_acpi_remove': ideapad-laptop.c:(.devexit.text+0x64a7): undefined reference to `backlight_device_unregister' drivers/built-in.o: In function `ideapad_acpi_add': ideapad-laptop.c:(.devinit.text+0x45e28): undefined reference to `backlight_device_register' To select backlight subsystem can prevent this error from happening.
