simple_strtoul() is deprecated; replace with kstrtoul() and kstrtouint().
Return an error if the value passed to the sysfs attribute is not
a number.
Drop the definition of strtoul() since it is no longer needed.

v2: An additional use of strtoul() was introduced with commit 4fa4616e.
Replace it as well.
