This patch adds basic SoundWire codec driver to support for
WCD9370/WCD9375 TX and RX devices.

The WCD9370/WCD9375 has Multi Button Headset Control hardware to
support Headset insertion, type detection, 8 headset buttons detection,
Over Current detection and Impedence measurements.
This patch adds support for this using wcd-mbhc apis.

Hi,

this pathc has reached -next, but I have a question.

If I'm correct, I can send a patch, but if the fix can be folded somewhere, this is also fine for me.

These irq have been requested wth devm_request_threaded_irq(), so either this free_irq should be removed, or devm_free_irq() should be used if the order is important.
