The conversion to the dma-mapping API in linux-2.6.11 was incomplete and left a virt_to_bus() call around. There have been a number of fixes for DMA mapping API abuse in this driver, but this one always slipped through. Change it to just use the existing dma_addr_t pointer, and make it use the correct types throughout the driver to make it easier to understand the virtual vs dma address spaces.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
