No, no, no!

Sorry, this was not the real rule I used for the strtoul case.  Instead I 
used the following:

@@
typedef ulong;
expression a,b;
{ulong,unsigned long,unsigned int,size_t} *c;
@@

-strict_strtoul
+kstrtoul
  (a,b,c)

But now I have seen that there is a separate function for integers, so I 
have made a rule to use that function when the type is unsigned int.

In every case see the type or real data and use appropriate function.
kstrtou8() for ports.

The type of the destination variable in all of these cases is unsigned 
long.  But maybe that is not enough information to make the 
transformation in the right way.

julia

This program creates lots of bogus patches in this case.
