[alsa-devel] [PATCH v3] ASoC: rt5645: Check if codec is initialized in workqueue handler

[Nicolas Boichat]

rt5645_jack_detect_work needs rt5645->codec to be initialized to
setup dapm pins. Also, reporting jack events is useless, as the
jacks cannot be set before the codec is ready.

Since we manually call the interrupt handler in
rt5645_set_jack_detect, the initial jack state will be reported
correctly, and dapm pins will be setup at that time.
