Always assign audio function pointers even if the display does not support audio. We need to properly disable the audio stream when when using a non-audio capable monitor. Fixes purple line on some hdmi monitors. 2. Check if a pin is in use by another encoder before disabling it. v2: make sure we've fetched the edid before checking audio and look up the encoder before calling audio_detect since connector->encoder may not be assigned yet. Separate pin and afmt. They are allocated at different times and have no dependency on eachother. v3: fix connector fetching in encoder functions v4: fix missed dig->pin check in dce6_afmt_write_latency_fields bugs: https://bugzilla.kernel.org/show_bug.cgi?id=93701 https://bugzilla.redhat.com/show_bug.cgi?id=1236337 https://bugs.freedesktop.org/show_bug.cgi?id=91041 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
