The use of le32_to_cpu() etc in this driver looks completely arbitrary. It may have made sense at some point, but it is not applied consistently, so this driver presumably won't work on big-endian kernel builds. Unfortunately it's unclear whether the type names or the calls to le32_to_cpu() are the correct ones. I'm taking educated guesses here and assume that most of the __le32 and __le16 annotations are correct, adding the conversion helpers whereever we access those fields. The exceptions are the 'fw_version' field that is always accessed as big-endian, so I'm changing the type here, and the 'hrrq' values that are accessed as little-endian, so I'm changing those the other way. None of these changes should have any effect on little-endian architectures like x86, but it addresses the sparse warnings.

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.
