In case __get_free_pages fails, the fix releases resources and
return -ENOMEM to avoid NULL pointer dereferences.
Also, the fix frees pages when video_register_device fails to

Add MMDC1 compatible string which is missing, and also set

Calling drm_atomic_set_fb_for_plane() (which gets a reference of the new

This series fixes the slow down in performance introduced by
"[PATCH v2] drm: Block fb changes for async plane updates" where async update
