Looking at the min() macro the above would become "count < sizeof(id)" rather
than "count <= sizeof(id)". I don't have more context into this code because I
can't find it in rproc-next nor today's linux-next, but it is something to look
into. The patch is also missing the minmax.h include for the min() macro.
Thanks,
