        Hi Sakamoto-san
This patch uses delayed_work with 0 delay, thus, call-back function will be called imminently. There was 0 jiffies delay between trigger <-> callback in my test.
Just use workqueue.
Additionally, it's better to add code comment about your strategy to wait for the 5 phase of word select clock.
I think I added it on ak4613_dai_trigger() ?
