Subject: drm/simple_kms_helper: Use drm_plane_helper_check_state()
X-Git-Tag: v5.15~12629^2~43^2~24
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4be12cc23d5030dcf7dfe055e26c0ab6e79dbb38;p=platform%2Fkernel%2Flinux-starfive.git

drm/simple_kms_helper: Use drm_plane_helper_check_state()

Replace the use of drm_plane_helper_check_update() with
drm_plane_helper_check_state() since we have a plane state.

I don't see any actual users of drm_simple_kms_helper yet, so
no actual plane clipping bugs to fix.
