Merge tag 'sunxi-drm-fixes-for-4.7-2' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into drm-fixesdrm-fixes-for-v4.7-rc7
Allwinner DRM driver fixes for 4.7, take 2 A new set of fixes for the sun4i driver, mostly related to vblank handling, and a minor fix to release a reference on the device tree nodes we're parsing in the probe logic. * tag 'sunxi-drm-fixes-for-4.7-2' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux: gpu: drm: sun4i_drv: add missing of_node_put after calling of_parse_phandle drm/sun4i: Send vblank event when the CRTC is disabled drm/sun4i: Report proper vblank
