* | ACPI / PM: Drop pm_message_t argument from device suspend callbackRafael J. Wysocki2012-07-01

* apple-gmux: Fix up the suspend/resume patchMatthew Garrett2012-06-01

| | | | | | | | | | | | | | | | | | | | | | | | | | | Acer Extensa 5235, TravelMate 5760 and Aspire 5750 laptop have broken _BCM implemenation, the AML code wrote value to EC register but firmware didn't change brighenss.

| | | | | | | | | | | | | | | | | | Loop through the list of SNC handles and run the proper initialization function for each of the known handles. Also return void in function where we are not checking the return value anyway. For notifications we also know which handle is linked to the event and the code becomes simpler to read with a switch rather than using convoluted ifs.

* sony-laptop: generalise ACPI calls into SNC functionsMattia Dongili2012-05-31
| | | | | | | | | | | All calls into the SNC device methods have zero or one arguments and return an integer or a buffer (some functions go as far as returning an integer _or_ a buffer depending on the input parameter...). This allows simplifying a couple of code paths and prepares the field for other users of functions returning buffers.

* toshiba_acpi: Add support for transflective LCDAkio Idehara2012-05-31
| | | | | | | | | | | Some Toshiba laptops have the transflective LCD and toshset can control its backlight state. I brought this feature to the mainline. To support transflective LCD, it's implemented by adding an extra level to the backlight and having 0 change to transflective mode. It was tested on a Toshiba Portege R500.

* toshiba_acpi: Only register backlight device when interface is read/writeSeth Forshee2012-05-31
| | | | | | | | | | | | Currently the backlight device is registered unconditionally, but many (probably most) Toshibas either don't support HCI_LCD_BRIGHTNESS or only support reading from it. This patch adds a test of HCI_LCD_BRIGHTNESS during initialization and only registers the backlight device if this interface supports both reads and writes.

* thinkpad-acpi: fix issuing duplicated key events for brightness up/downAlex Hung2012-05-31
| | | | | | | | | | The tp_features.bright_acpimode will not be set correctly for brightness control because ACPI_VIDEO_HID will not be located in ACPI. As a result, a duplicated key event will always be sent. acpi_video_backlight_support() is sufficient to detect standard ACPI brightness control.

* xo1-rfkill: only act when blocked state is changedDaniel Drake2012-05-31
| | | | | | | | | | | | | | | | | The XO-1 rfkill driver should only send EC commands when changing between blocked/unblocked state. The rfkill switch is asked to be unblocked on every resume (even when the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET command here upsets the resume sequence of the libertas driver. Adding the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume behaviour. The rfkill state is maintained by the hardware over suspend/resume so no extra consideration is needed here.
