6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ankit Nautiyal <ankit.k.nautiyal@xxxxxxxxx>
[ Upstream commit 4466302262b38f5e6c65325035b4036a42efc934 ]
Currently we support Adaptive sync operation mode with dynamic frame
rate, but instead the operation mode with fixed rate is set.
This was initially set correctly in the earlier version of changes but
later got changed, while defining a macro for the same.
Fixes: a5bd5991cb8a ("drm/i915/display: Compute AS SDP parameters")
