[FFmpeg-devel] [PATCH 06/26] avfilter/af_sidechaincompress: Remove always-false samplerate check

[Andreas Rheinhardt]

This filter uses ff_set_common_all_samplerates().
Also don't overwrite outlink->sample_rate in config_output;
it is harmless, because it is overwritten with the value it already
had, but it is an API violation.
