It gets a little confusing with the first variable being initialized, but the subsequent variables being uninitialized.

And in the next patch ([PATCH 4/7] avcodec/pcm: Don't allocate LUT when unused), with the introduction of PCM_CODEC_EXT(), the alignment of PCM_CODEC/PCM_DECODER/PCM_CODEC_EXT is lost.
