[ Upstream commitd6834b4b58] The media controller core prints a warning when an entity is registered without a function being set. This affects the uvcvideo driver, as the warning was added without first addressing the issue in existing drivers. The problem is harmless, but unnecessarily worries users. Fix it by mapping UVC entity types to MC entity functions as accurately as possible using the existing functions.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
