[ Upstream commit 34935701b7ed1a1ef449310ba041f10964b23cf4 ]
[Why&How] stream->adjust will be overwritten by update->crtc_timing_adjust. We should set update->crtc_timing_adjust->timing_adjust_pending and then overwrite stream->adjust. Reset update->crtc_timing_adjust->timing_adjust_pending after the assignment.
