drm: make drm_atomic_set_mode_prop_for_crtc() more reliable

Browse source

commit 6709887c44 upstream.

drm_atomic_set_mode_prop_for_crtc() does not clear the state->mode, so
old data may be left there when a new mode is set, possibly causing odd
issues.

This patch improves the situation by always clearing the state->mode
first.
