One unintended consequence of this change is that it'll now accept a
negative integer parameter.  I'll rework this to have the same behavior
as before.

BTW, one question, is the __must_check really needed on kstrtoint?
Wouldn't it be acceptable to rely on kstrtoint to not update resume_delay
if it's unable to parse an integer out of the string?  Couldn't that be
a sufficient effect without requiring checking the return?

Thanks,

Sebastian
