Subject: media: venus: helpers: Done buffers per queue type
Author: Stanimir Varbanov <stanimir.varba...@linaro.org>
Date: Tue Mar 31 17:47:38 2020 +0200
Currently calling venus_helper_buffers_done() will return buffers to
user for both capture and output queues in the same call. This is
wrong because both queues are really separate and calling
stop_streaming on one queue shouldn't return buffers for the other.
Solve this by add a new queue type argument and fix the clients of
the helper function.
