If anyone has any objections, please let me know. ------------------ From: Satish Babu Patakokila commit 01b8cedfd0422326caae308641dcadaa85e0ca72 upstream. 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.
