ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at gmail.com> | Sat Aug 22 03:29:25 2020 +0200| [080d2c67f540908e48d1e0f482c057e52a7fad7a] | committer: Andreas Rheinhardt

avfilter/af_anequalizer: Don't allocate outpad names

These names are always the same, so not using duplicates saves
allocations, checks for the allocations as well as frees.
