Serge Semin 95e060e68b usb: usb251xb: Add an empty hub' i2c-bus segment checker ... It's pointless to scan the hub' i2c-bus segment if GPIOs aren't supported by the system, since no GPIO-driven reset could be cleared by the driver then. Moreover if CONFIG_GPIOLIB is disabled the gpio_chip structure definition won't be available, which causes the incomplete type pointer dereference compilation error. In order to fix this we need to create an empty usb251x_check_gpio_chip() method returning zero, so the driver would skip the i2c-bus segment checking and proceed with further probing in this case.
