I'm afraid it should be like the following.
+ b = (s32)(div64_s64(((s64) freq) << 20, state->cfg.xtal_freq)
+ - (((s64) a) << 20));
Are you talking about coding style?
It is calculation order of operators. '/' vs. '-'
Instead of using something like:
var = foo_func(a, c
- b);
We generally use:
var = foo_func(a,
c - b);
As it is quicker for reviewers to read.
regads,
