ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at gmail.com> | Mon Oct 12 04:08:07 2020 +0200| [7b6acfa68f034c6e2cf2455dbc0f96d959ef36b0] | committer: Andreas Rheinhardt

avcodec/speedhq: Don't pretend reading DC can fail

It can't, because the tables used don't have any loose ends. This also
fixes a bug in the only caller of decode_dc_le(): It didn't check the
return value.
