The HUAWEI USB-C headset (VID:0x12d1, PID:0x3a07) reported it supports 96khz. However there will be some random issue under 96khz. Not sure if there is any alternate setting could be applied. Hence 48khz is suggested to be applied at this moment.

This means firmware version of the headset as far as I know..
OK, then it's useful.
Sorry I'll check the compile error and resend later.
I guess the only needed change is to replace udev with chip->dev.
