[FFmpeg-devel] [PATCH 3/3] avcodec/hevcdec: Return immediately upon hevc_init_context() failure

[Andreas Rheinhardt]

This function is only called from the decoder's init function
and given that this decoder has FF_CODEC_CAP_INIT_CLEANUP set,
hevc_decode_free() is called automatically (currently it would
be called twice with the second call being redundant).
