From: Olivier Moysan <olivier.moysan@xxxxxx> commit 3b7658679d88b5628939f9bdc8e613f79cd821f9 upstream. Changing input state in iec capture control is not safe, as the pin state may be changed concurrently by ASoC framework. Remove pin state handling in iec capture control. Note: This introduces a restriction on capture control, when pin sleep state is defined in device tree. In this case channel status can be captured only when an audio stream capture is active.
