usb: select USB_COMMON for usb role switch config
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.
