Here are some little fixes for rockchip drm, looks good for me, and seems there is no doubt on them, So I'd like you can land them.
* 'drm-rockchip-next-fixes-05-03' of https://github.com/markyzq/kernel-drm-rockchip:
drm/rockchip: vop: Initialize vskiplines to zero
drm/rockchip: vop: fix iommu crash with async atomic
drm/rockchip: support non-iommu buffer path
drm/rockchip: get rid of rockchip_drm_crtc_mode_config
drm/rockchip: inno_hdmi: fix an error code
drm/rockchip: don't leak iommu mapping
drm/rockchip: remove redundant statement

u32 val;
