Okay, rereading the original commit log from Cihhao Chen I gather
Samsung USBC Headset (AKG) with VID/PID (0x04e8/0xa051) actually has
two clock selectors and only one clock source.

Correct me if I'm wrong.

This is complicated by the fact I haven't been able to find a lsusb -v
of Samsung USBC Headset (AKG) with VID/PID (0x04e8/0xa051)

Even so, my proposition still stands: devices with only one clock
source and only one clock selector should be able to handle us
selecting the clock selector to the only clock source.
