016a255b7835ee7e49a3eba3c14ba0bc0221a4f8 is the first bad commit
commit 016a255b7835ee7e49a3eba3c14ba0bc0221a4f8
Author: Alex Deucher <alexander.deucher@xxxxxxx>
Date: Tue Apr 7 09:52:42 2015 -0400
drm/radeon: only mark audio as connected if the monitor supports it (v3)
commit 0f55db36d49d45b80eff0c0a2a498766016f458b upstream.
Otherwise the driver may try and send audio which may confuse the
monitor.
v2: set pin to NULL if no audio
v3: avoid crash with analog encoders
