2013-04-18Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86Linus Torvalds
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"
2013-04-18Revert "hp-wmi: Add support for SMBus hotkeys"Matthew Garrett
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 <matthew.garrett@nebula.com>
2013-04-17thinkpad-acpi: kill hotkey_thread_mutexOleg Nesterov
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().

2013-02-27hp-wmi: fix handling of platform deviceDmitry Torokhov
The driver will not quite work if someone unbinds the platform device from the platform driver via sysfs (moreover it will bomb is the driver built into the kernel as hp_wmi_bios_remove is marked as __exit and will not be present in the kernel). To fix it let's use platform_driver_probe() instead of platform_driver_register(), which disables binding/unbinding via sysfs. This also allows us to mark hp_wmi_bios_setup as __init and discard it once module is initialized.

2013-02-24asus-wmi: add display toggle quirkAceLan Kao
For machines with AMD graphic chips, it will send out WMI event and ACPI interrupt at the same time while hitting the hotkey. BIOS will notify the system the next display output mode throught WMI event code, so that windows' application can show an OSD to tell the user which mode will be taken effect. User can hit the display toggle key many times within 2 seconds to choose the mode they want. After 2 seconds, WMI dirver should send a WMIMethod(SDSP) command to tell the BIOS which mode the user chose. And then BIOS will raise another ACPI interrupt to tell the system to really switch the display mode. In Linux desktop, we don't have this kind of OSD to let users to choose the mode they want, so we don't need to call WMIMethod(SDSP) to have another ACPI interrupt. To simplify the problem, we just have to ignore the WMI event, and let the first ACPI interrupt to send out the key event. For the need, here comes another quirk to add machines with this kind of behavior. When the WMI driver receives the display toggle WMI event, and found the machin is in the list, it will do nothing and let ACPI video driver to report the key event.
