3.16.65-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Laurent Pinchart <[email protected]> commit 3d61fe5f59dd3e6f96fc0772156d257cb04dc656 upstream. The drm_vblank_init() takes the total number of CRTCs as an argument, but the rcar-du driver passes a bitmask of the CRTC indices. Fix it.
