[FFmpeg-devel] [PATCH v2] avcodec/vvc/refs: remove early return

[Marvin Scholz]

The ret value is checked later on again, so this check
is redundant and would cause the frame to not be unrefd on
failure as well.

So remove this check and add one before av_frame_remove_side_data
to ensure it is not called with an invalid frame.

Fix CID 1648350
