drm: Wrap the check for atomic_commit implementation
This check is useful for drivers that do not have DRIVER_ATOMIC set but have atomic modesetting internally implemented. Wrap the check into a function since this is used in many places and as a bonus, the function name helps to document what the check is for. v2: Change return type to bool (Ville) Move the function drm_atomic.h (Daniel) Fixed comment marker for documentation Suggested-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> [danvet: Move back to drmP.h because include hell.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1482396643-32456-1-git-send-email-dhinakaran.pandiyan@intel.com
