popcornmix f71efe646c vc4_hdmi_phy: Fix offset calculation
The original firmware code worked with float and did
   offset = ((vco_freq / fref * 2) * (1 << 22));
   offset >>= 2;

In this code it's all integer so doing the integer divide before the shift loses lots of precision

This fixes the issue of 1080p59.94 mode having 59.64 fps

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.
