Ok, I've removed it from drviers/usb/common/common.c.

We don't need it. It will be enabled when USB_GADGET or USB is enabled.
It should cover all cases.  

menuconfig USB_GADGET
	tristate "USB Gadget Support"
	select USB_COMMON

config USB
	tristate "Support for Host-side USB"
	depends on USB_ARCH_HAS_HCD
	select USB_COMMON
