-Subject: [PATCH 0738/4131] drm/amd/display: Move verify link cap after read
- edid
-
-DP link layer test 400.1.1 fails intermittently.
-The test device will pull hpd low immediately
-after verify link cap.
-Driver reads edid when hpd low that causes the test to fail.
-
-Move read edid before verify link cap, so driver will
-read edid before starting link training
