write_reg returns 0 on success, we can make it more explicit by returning number 0 instead of result variable. read_reg should return 0 on success since this is a more common pattern. The user of read_reg has been clean-up and should be at the same commit. Signed-off-by: Gimcuan Hui <gimcuan@gmail.com> Signed-off-by: Johan Hovold <johan@kernel.org>
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.
