drm/sun4i: crtc: Call drm_crtc_vblank_on / drm_crtc_vblank_offdrm-misc-fixes-2018-03-07
Make sure that the CRTC code will call the enable/disable_vblank hooks. Otherwise, since the refcounting will be off, we might end up in a situation where the vblank management functions are called while the CRTC is off.
