-Subject: [PATCH 1009/4131] drm/amd/display: do not reset lane count in EQ
- fallback
-
-[Description]
-According to DP1.4 specs we should not reset lane count back
-when falling back in failing EQ training.
-This causes PHY test pattern compliance to fail as infinite LT
-when LT fails EQ to 4 RBR and fails CR in a loop.
