ASoC: compress: Derive substream from stream based on direction (01b8cedf) · Commits · 戴 / test

Currently compress driver hardcodes direction as playback to get substream from the stream. This results in getting the incorrect substream for compressed capture usecase. To fix this, remove the hardcoding and derive substream based on the stream direction. Signed-off-by:
