[PATCH] USB: gadget driver section fixups
This adds __init section annotations to gadget driver bind() routines to remove calls from .text into .init sections (for endpoint autoconfig). Likewise it adds __exit section annotations to their unbind() routines. The specification of the gadget driver register/unregister functions is updated to explicitly allow use of those sections.
