load is an unsigned integer. So, it is always bigger or equal to zero, as reported by gcc: drivers/media/i2c/max2175.c: In function 'max2175_refout_load_to_bits': drivers/media/i2c/max2175.c:1272:11: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits] if (load >= 0 && load <= 40) ^~ Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
