During reboot, when the CS42L42 powers down, pops and clicks may occur due to the codec not being shutdown gracefully. This can be fixed by going through the suspend sequence, which shuts down the codec cleanly inside the reboot_notify hook, which is called on reboot.

I hold this one for now, as there is a fix series that deprecates the reboot_notify callback of HD-audio by forcibly doing runtime-suspend at shutdown. Please check the three patches in https://bugzilla.kernel.org/show_bug.cgi?id=214045
I'm going to submit those soon in anyway.
thanks,
