The routines used by the UDC core to interface with the kernel's device model, namely usb_add_gadget_udc(), usb_add_gadget_udc_release(), and usb_del_gadget_udc(), provide access to only a subset of the device model's full API. They include functionality equivalent to device_register() and device_unregister() for gadgets, but they omit device_initialize(), device_add(), device_del(), get_device(), and put_device(). This patch expands the UDC API by adding usb_initialize_gadget(), usb_add_gadget(), usb_del_gadget(), usb_get_gadget(), and usb_put_gadget() to fill in the gap. It rewrites the existing routines to call the new ones.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
