[FFmpeg-devel] [PATCH] libavfilter/dnn/dnn_backend_tf: Remove redundant av_freep() to avoid double free

[FFmpeg-devel] [PATCH] libavfilter/dnn/dnn_backend_tf: Remove redundant av_freep() to avoid double free

[Jiasheng Jiang]

Remove redundant av_freep() to avoid double free since task will be freed in dnn_free_model_tf() after the success of ff_queue_push_back().

Fixes: af052f9066 ("lavfi/dnn: fix mem leak in TF backend error handle")
