The data transfer mode that corresponds to the 'xfer_mode' parameter for ata_xfer_mode2shift() is a 8-bit *unsigned* value. Using *unsigned long* to declare the parameter leads to a problematic implicit *int* to *unsigned long* cast and was most probably a result of a copy/paste mistake -- use the 'u8' type instead, as in ata_xfer_mode2mask()...

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.
