Merge tag 'driver-core-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core updates from Greg KH:
 "Here's the big driver-core pull request for 3.17-rc1.

  Largest thing in here is the dma-buf rework and fence code, that
  touched many different subsystems so it was agreed it should go
  through this tree to handle merge issues.  There's also some firmware
  loading updates, as well as tests added, and a few other tiny changes,
  the changelog has the details.

  All have been in linux-next for a long time"

+What:		/sys/bus/platform/devices/.../driver_override
+Date:		April 2014
+Contact:	Kim Phillips <kim.phillips@freescale.com>
+Description:
+		This file allows the driver for a device to be specified which
+		will override standard OF, ACPI, ID table, and name matching.
+		When specified, only a driver with a name matching the value
+		written to driver_override will have an opportunity to bind
+		to the device.  The override is specified by writing a string
+		to the driver_override file (echo vfio-platform > \
+		driver_override) and may be cleared with an empty string
+		(echo > driver_override).  This returns the device to standard
+		matching rules binding.  Writing to driver_override does not
+		automatically unbind the device from its current driver or make
+		any attempt to automatically load the specified driver.  If no
+		driver with a matching name is currently loaded in the kernel,
+		the device will not bind to any driver.  This also allows
+		devices to opt-out of driver binding using a driver_override
+		name such as "none".  Only a single driver may be specified in
+		the override, there is no support for parsing delimiters.
