Clang warns when a variable is assigned to itself.
drivers/media/pci/bt8xx/bttv-driver.c:2043:13: warning: explicitly
assigning value of variable of type '__s32' (aka 'int') to itself
[-Wself-assign]
min_height = min_height;

There doesn't appear to be any good reason for this and this statement
was added in commit e5bd0260e7d3 ("V4L/DVB (5077): Bttv cropping
support") back in 2007. Just remove it.

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.
