I'll take this patch as-is, and someone can send a follow-up to convert the whole file to kstrtoul(). cheers

If we are going to change one might as well do them all at once. If the original
submitter wants to send the follow up that is fine, or I can send a patch when I
have a minute.

I guess there are several other uses of simple_strtoul() in this file.
Not sure if it's worth changing them all, just this one, or just the
patch below as-is.

Michael, if you want this:

If you don't mind, edit the subject to follow the convention, e.g.,
PCI: rpaphp: Remove unused variable 'value'
Apparently simple_strtoul() is deprecated and we're supposed to use
kstrtoul() instead. Looks like kstrtoul() might simplify the code a
little, too, e.g.,
if (kstrtoul(drc_type, 0, ) == 0)
return 1;
return 0;
