As appears from an analysis of to_clkrc() helper code after its pclk_limit argument has been dropped, its result no longer depends on another argument - pclk_max. Moreover, assuming that a constant value of FRAME_RATE_MAX is always used as a denominator of the only significant argument left - a struct v4l2_fract, the result in fact depends only on the numerator value of that argument. As a further consequence, it no longer makes sense to recalculate frame intervals by converting them forth and back with a GET_CLKRC_DIV(to_clkrc(tpf)) construct. Drop use of GET_CLKRC_DIV() on results of to_clkrc() where possible - use the frame interval value directly. Furthermore, replace the to_clkrc() helper function with a simple macro and update its users to always use FRAME_RATE_MAX as frame interval denominator and pass only its numerator as an argument.

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.
