The simple_strtol() function is deprecated in some situation since
it does not check for the range overflow. Use kstrtoint()/kstrtoul()
instead.
Attention, if the end of the input string isn't '\n', simple_strtol() will
ignore following characters and return the value but kstrtoint()/kstrtoul()
will return an error code.
