drm/radeon: be quiet when no SAD block is found
It is fine for displays without audio functionality to not provide any SAD block in their EDID. Do not log an error in that case, just return quietly. Inspired by a similar fix to the amdgpu driver in the context of bug fdo#107825: https://bugs.freedesktop.org/show_bug.cgi?id=107825 Signed-off-by: Jean Delvare <jdelvare@suse.de> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: "Christian König" <christian.koenig@amd.com> Cc: "David (ChunMing) Zhou" <David1.Zhou@amd.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
