The PCM config space refine codes touch the parameter rmask and cmask bits when the given config parameter is changed. But in most places it checks only whether the changed value is non-zero or not, and they don't consider whether a negative error value is returned. This will lead to the incorrect update bits set upon the error path. Fix the codes to check properly the return code whether it's really updated or an error.

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.
