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.

The DAC register is 16 bits wide, so the value passed by write_raw() should be checked against that limit. Rather than hardcoding the 16-bit maximum value limit, use a define to improve readability and make the intention of the code clearer. The explicit cast is also avoided by instead explicitly checking for negative values. Suggested-by:Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by:
