Is it possible to tie this to a commit?
This is a u64 variable getting divided somewhere or maybe the divisor is a u64?
But there haven't been any recent changes to the driver so probably the change
happened in a header file? I looked the differences between the preprocessed
.i files from before and after and nothing jumped out at me.
I don't have a copy of gcc-8...
regards,
