[PATCH 1/6] ASoC: codec2codec: run callbacks in order

[Jerome Brunet]

When handling dai_link events on codec to codec links, run all .startup()
callbacks on sinks and sources before running any .hw_params(). Same goes
for hw_free() and shutdown(). This is closer to the behavior of regular
dai links
