[FFmpeg-devel] [PATCH 7/7] avcodec/hevc/hevcdec: initialize qp_y_tab

[Michael Niedermayer]

This does not replicate on my setup, thus this is a blind fix based on ossfuzz trace

Fixes: use of uninitialized value
Fixes: 71747/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_HEVC_fuzzer-5427736120721408

Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg
