We currently crash if usb_add_gadget_udc_release() fails, since the udc->done is not initialized until in the remove function. Furthermore, on module removal the udc data is accessed although the release function is already triggered by usb_del_gadget_udc() early in the function. Fix by rewriting the release and remove functions, basically moving all the cleanup into the release function, and doing the completion only in the module removal case. The patch fixes omap_udc module probe with a failing gadged, and also allows the removal of omap_udc. Tested by running "modprobe omap_udc; modprobe -r omap_udc" in a loop.

README
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.
