The Prefix CCW is not mandatory and raw I/O can also be issued without it. Check whether the Prefix CCW is supported and if not use the combination of Define Extent and Locate Record Extended instead. While at it, sort the variable declarations, replace the gotos with early exits, and remove an error check at the end which is irrelevant. Also, remove the XRC check as it is not relevant for raw I/O.

README
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.
