Subject: [PATCH] drm/atomic-helper: fix parameter order in
drm_format_conv_state_copy() call
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Old and new state parameters are swapped, so the old state was cleared
instead of the new duplicated state.
Fixes: 903674588a48 ("drm/atomic-helper: Add format-conversion state to shadow-plane state")
