commit7c07553807upstream. It is unable to use configfs to attach more than one gadget. When attaching the second gadget, it always fails and the kernel message prints out: Error: Driver 'configfs-gadget' is already registered, aborting... UDC core: g1: driver registration failed: -16 This commit fixes the problem by using the gadget name as a suffix to each configfs_gadget's driver name, thus making the names distinct.

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.
