The controller expects all data it sends/receives to be little-endian. Therefore, the packet struct definitions should use the __le16/32/64 types. Once those are correct, sparse reports several issues with the driver code, which are fixed here as well. The main issue observed was at the call to scsi_set_resid(), where the byteswapped parameter would eventually trigger the alignment check at drivers/scsi/sd.c:2009. At that point, the kernel would continuously complain about an "Unaligned partial completion", and no further I/O could occur. This gets the controller working on big endian powerpc64.

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.
