[PATCH 1/2] ASoC: dmaengine: Drop unused iov_iter for process callback
by Takashi Iwai 01 Sep '23

01 Sep '23

Passing the iov_iter to the process callback is rather buggy, as the iterator has been already processed for playback. Similarly, it makes the copy for capture buggy after the process callback reading the iterator out. Moreover, all existing process callbacks don't refer to the passed iterator at all. So, it's better to drop the argument from the process callback.
