Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "Two build fixes, one for VC4, one for nouveau where the ARM only code
  is doing something a bit strange.  While people are discussing that,
  just workaround it and fix the build for now.  The code in question
  will never get used on anything non-ARM anyways.

  Also one fix for AST that SuSE had been hiding in their kernel, that
  allows all fbdev apps to work on that driver"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/nouveau: fix build failures on all non ARM.
  drm/ast: Initialized data needed to map fbdev memory
  drm/vc4: Add dependency on HAVE_DMA_ATTRS, and select DRM_GEM_CMA_HELPER
