[FFmpeg-devel] [PATCH] libavcodec/sonic.c: Add check for av_calloc()

[Jiasheng Jiang]

Add check for the return value of av_calloc() to avoid
potential NULL pointer dereference.

Fixes: 54f5fd22ea ("new opensource lossy/lossless audio codec based on speech compression techniques (actually based on bonk)")
