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.

In the (unlikely) event that community->ngpps is zero, or if every
gpp->gpio_base is less than zero, then an ininitialized value in
ret is returned by function intel_gpio_add_pin_ranges. Fix this by
ensuring ret is initialized to zero. It's a moot point, but I think
it is worthwhile ensuring this corner case is fixed.
