It is at: include/linux/usb/otg.h,
==============
#ifdef CONFIG_NOP_USB_XCEIV
extern void usb_nop_xceiv_register(void);
extern void usb_nop_xceiv_unregister(void);
#endif
================
But one of the David's queued patch [1] removes the #ifdef part.
[1] http://marc.info/?l=linux-usb&m=123852883820097&w=2

Is it ok to add it back in this patch?

David, what's your comment on this?
