[PULL] drm-misc-next

[Thomas Zimmermann <tzimmermann@suse.de>]

Hi Dave, Sima,

this is the weekly PR for drm-misc-next. It has quite a number of
highlights:

* There is the new device wedge event, which allows drivers to report
  unresponsive hardware to user space via a uevent. Drivers for AMD and
  Intel HW already use the functionality.

* The i2c subdirectory has been removed after all code has been moved
elsewhere.

* Atomic helpers now support asyncronous pageflips on arbitrary planes.
  Amdgpu already supports this.

And of course there's the usual amount of fixes, cleanups and small
additions.

Best regards
Thomas
