The driver uses a mixture of signed and unsigned integer variables for
holding arrays lengths and indices, which gives rise to the following
sparse warnings when the addresses of signed variables are passed to
functions expecting pointers to unsigned integers:

This patch fixes those warnings by converting those signed variables to
unsigned as follows:
* changed the types of a number of index and length variables from
signed to unsigned integer types.
* changed the return-types of a couple of functions that return length
values which are assigned to one of these variables from signed to
unsigned integer types.

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.
