[ Upstream commit d9fecd096f67a4469536e040a8a10bbfb665918b ]
Now we keep a reference to the active fh for any call to uvc_ctrl_set,
regardless if it is an actual set or if it is a just a try or if the
device refused the operation.
We should only keep the file handle if the device actually accepted
applying the operation.

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.
