openbsd-ports/audio/libdca/patches/patch-libdca_tables_huffman_h
ajacoutot acdd092453 Some bug fixes from upstream: 
- Fix random crashes caused by invalid 32-bit shifts on 32-bit values.
- Mark tables as static constants.
- Change output normalisation factor from 3/2 to sqrt(2).
- Sanity check for subframes and prim_channels to avoid crashes with invalid streams.
- Avoid crashing with invalid frames setting a bitalloc_huffman component to 7.

While here, tweak COMMENT and remove USE_GROFF.
