[PATCH AUTOSEL 6.0 28/30] drm/amd/display: Don't return false if no stream

From: Sasha Levin
Date: Sun Nov 06 2022 - 12:06:44 EST


From: Alvin Lee <Alvin.Lee2@xxxxxxx>

[ Upstream commit abe4d9f03fae76c9650b0d942faf6990b35c377b ]

pipe_ctx[i] exists even if the pipe is not
in use. If the pipe is not in use it will
always have a null stream, so don't return
false in this case.
