Subject: [PATCH AUTOSEL 5.15 57/68] drm/amd/display: Fixed DSC would not PG after removing DSC stream

From: Yi-Ling Chen <Yi-Ling.Chen2@....com>

[ Upstream commit 2da8f0beece08a5c3c2e20c0e38e1a4bbc153f9e ]

[WHY]
Due to pass the wrong parameter down to the enable_stream_gating(),
it would cause the DSC of the removing stream would not be PG.

[HOW]
To pass the correct parameter down th the enable_stream_gating().
