Fix this smatch error: saa7134-video.c:1286 saa7134_g_fmt_vid_overlay() error: we previously assumed 'f->fmt.win.clips' could be null (see line 1279) This is actually a false error since if f->fmt.win.clips is NULL, clipcount will be set to 0, so the clips array won't be touched, but it doesn't hurt to make this explicit in the code.

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.
