This patch moves from a struct declaration for the DMA controller registers to macros with offests to the base address. This is mainly done to remove the sparse warnings, since the function parameter of ioread32/iowrite32 is "void __iomem *" instead of a pointer to struct members. With this patch applied, no sparse warning is seen anymore. Please note that the struct for the descriptors is still kept in place, as the code largely accesses the struct members as internal variables before the complete struct is copied into the descriptor FIFO of the DMA controller. Additionally this patch also removes two warnings "variable xxx set but not used" seen when compiling with "W=1". The registers need to be read to flush the response FIFO, but nothing needs to be done with them. So the code is correct here and the warning is a false one.

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.
