I'm trying to come up with a test. I did look into the code and saw that
the pointer to the string moves as it's being parsed, and the parsing stops
when the string is no longer a number. So I think it's good to use this
function to replace simple_strtoul(), as kstrtoul() has an overflow check
as a plus.
