    usb: select USB_COMMON for usb role switch config · 602f4fb7
    Arnd Bergmann authored
    The new axp288 extcon driver has no dependency on USB itself but
    calls the usb role switch helper functions. This causes a link error
    when USB_COMMON is disabled, as that subdirectory never gets entered:
    
    drivers/extcon/extcon-axp288.o: In function `axp288_usb_role_work':
    extcon-axp288.c:(.text+0x47b): undefined reference to `usb_role_switch_set_role'
    extcon-axp288.c:(.text+0x498): undefined reference to `usb_role_switch_get_role'
    drivers/extcon/extcon-axp288.o: In function `axp288_extcon_probe':
    extcon-axp288.c:(.text+0x675): undefined reference to `usb_role_switch_get'
    extcon-axp288.c:(.text+0x6d1): undefined reference to `usb_role_switch_put'
    drivers/extcon/extcon-axp288.o: In function `axp288_put_role_sw':
    extcon-axp288.c:(.text+0x1c): undefined reference to `usb_role_switch_put'
    
    There are multiple ways of fixing this, I chose to 'select USB_COMMON',
    since that is how we solved the same problem for other helpers like
    USB_LED_TRIG or PHY drivers.
