div_u64() does a 64-by-32 division, while the divisor max2175.xtal_freq is unsigned long, thus 64-bit on 64-bit platforms. Hence the proper function to call is div64_ul(). Note that this change does not have any functional impact, as the crystal frequency must be much lower than the 32-bit limit anyway. On 32-bit platforms, the generated code is the same. But at least on arm64, this saves an AND-instruction to truncate xtal_freq to 32-bit.

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.
