From: Konstantin Porotchkin <[email protected]> Use local static counter for maintaining the COMPHY chip-ID upon its initialization. The dev->seq originally used as the COMPHY chip-ID depends on the device tree scan order and produces wrong results that breaks the deficated PHYs init flow, which in turn breaks the USB support.
