Subject: drm/amd/display: Fix refresh rate issue on Club 3D
Git-commit: e9a7d236eaaeb1cdfe20e583e2e1899b26d7469c
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
Recently we introduced a patch for fixing an MST issue, but it caused a
regression on Club 3D since we could not set a refresh rate higher than
60Hz. This commit fixes this issue by adding a proper check after
validating the stream.
Fixes: f04d275d94e164 ("drm/amd/display: add mst port output bw check")
