[GIT PULL] Armada DRM fixes

[Russell King]

David,

Please incorporate the latest Armada DRM fixes, which can be found at:

  git://ftp.arm.linux.org.uk/~rmk/linux-arm.git drm-armada-fixes

with SHA1 178e561f514fca4863c06a4af3501172e5627eb1.

Three changes for the Armada DRM driver:
1. Add back the flags which tell the DRM core that we can do vblank.  This
   was removed in error during the recent restructuring, and came to light
   while trying textured Xv rendering.

2. Fixing a refcount leak with Xv overlay.

3. As per recent discussion, the drm_vblank_pre_modeset() calls can cause
   deadlock with other changes to generic code.  This change prevents those
   deadlocks by switching to the drm_crtc_vblank_*() calls instead.

This will update the following files:

 drivers/gpu/drm/armada/armada_crtc.c | 21 ++++++++++-----------

Many thanks.
