6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Adam Ford <aford173@xxxxxxxxx>
commit 739214dd1c209e34323814fb815fb17cccb9f95b upstream.
The Kernel test robot returns the following warning:
do_div() does a 64-by-32 division, please consider using div64_ul instead.
To prevent the 64-by-32 divsion, consolidate both the multiplication
and the do_div into one line which explicitly uses u64 sizes.
