With the patch "588b9e85609b (usb: gadget: uvc: add v4l2 enumeration api
calls)" the driver is keeping a list of configfs entries currently
configured. The list is used in uvc_v4l2 on runtime.
The driver now is giving back the list item just after it was referenced
with config_item_put. It also calls config_item_put on uvc_free, which
is the only and right place to give back the reference. This patch fixes
the issue by removing the extra config_item_put in uvc_alloc.
Fixes: 588b9e8560 (usb: gadget: uvc: add v4l2 enumeration api calls)

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.
