The return value from the call to cht_wc_leds_find_freq() is int. However, the return value is being assigned to an unsigned int variable 'ctrl', so making it an int. Eliminate the following warning: drivers/leds/leds-cht-wcove.c:236 cht_wc_leds_set_effect() warn: unsigned 'ctrl' is never less than zero.

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.
