While in this particular case it would not be a (critical) issue, the pattern itself is bad and error prone in case somebody blindly copies to their code. Don't cast parameter to unsigned long pointer in the bit operations. Instead copy to a local variable on stack of a proper type and use. Note, new compilers might warn on this line for potential outbound access.

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.
