From: Mikita Lipski <mikita.lipski@xxxxxxx>
We shouldn't compare int with unsigned long to find the max value
and since we are not expecting negative value returned from
compute_offset we should make this function return unsigned long
so we can compare the values when computing rc parameters.
v2: Modified function parameters to unsigned type for type
consistency
