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.
