Merge tag 'platform-drivers-x86-v3.19-2' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86

Pull platform driver fix from Darren Hart:
 "Revert keyboard backlight sysfs support and documentation.

  The support for the dell-laptop keyboard backlight was flawed and the
  fix:

        https://lkml.org/lkml/2015/1/14/539

  was more invasive that I felt comfortable sending at RC5.

  This series reverts the support for the dell-laptop keyboard backlight
  as well as the documentation for the newly created sysfs attributes.

  We'll get this implemented correctly for 3.20"

-What:		/sys/class/leds/dell::kbd_backlight/start_triggers
-Date:		December 2014
-KernelVersion:	3.19
-Contact:	Gabriele Mazzotta <gabriele.mzt@gmail.com>,
-		Pali Rohár <pali.rohar@gmail.com>
-Description:
-		This file allows to control the input triggers that
-		turn on the keyboard backlight illumination that is
-		disabled because of inactivity.
-		Read the file to see the triggers available. The ones
-		enabled are preceded by '+', those disabled by '-'.
-
-		To enable a trigger, write its name preceded by '+' to
-		this file. To disable a trigger, write its name preceded
-		by '-' instead.
-
-		For example, to enable the keyboard as trigger run:
-		    echo +keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
-		To disable it:
-		    echo -keyboard > /sys/class/leds/dell::kbd_backlight/start_triggers
-
-		Note that not all the available triggers can be configured.

-Date:		December 2014
-KernelVersion:	3.19
-Contact:	Gabriele Mazzotta <gabriele.mzt@gmail.com>,
-		Pali Rohár <pali.rohar@gmail.com>
-Description:
-		This file allows to specify the interval after which the
-		keyboard illumination is disabled because of inactivity.
-		The timeouts are expressed in seconds, minutes, hours and
-		days, for which the symbols are 's', 'm', 'h' and 'd'
-		respectively.
-
-		To configure the timeout, write to this file a value along
-		with any the above units. If no unit is specified, the value
-		is assumed to be expressed in seconds.
-
-		For example, to set the timeout to 10 minutes run:
-		    echo 10m > /sys/class/leds/dell::kbd_backlight/stop_timeout
-
-		Note that when this file is read, the returned value might be
-		expressed in a different unit than the one used when the timeout
-		was set.
-
-		Also note that only some timeouts are supported and that
-		some systems might fall back to a specific timeout in case
-		an invalid timeout is written to this file.
