Are you suggesting a change to the "unsigned long flags" in struct
resource, or a different change to pnp_resource_type()?

The struct resource change sounds reasonable, but I think neither
Rene nor I want to sign up to do that right now.

Whatever we have in struct resource, I think it makes sense to use
the same type everywhere we reference the "flags" element.  I think
you're saying "it doesn't matter in this case that we use different
types."  But I, as a code reader, would rather not have to spend the
mental energy to convince myself that you're right.
