I think the second warning is simply additional information attached
to the 1st to give context?

I noticed this issue but felt changing the type of this field would
sit outside the purview of this patch as then I'm not only changing
the type of mmio750 and code that *directly* interacts with this
variable, but also code that indirectly interacts with it, so I felt
that should perhaps be a separate patch.

I'd love to additionally provide some further patches to help out with
issues here too, incidentally! I will try to prepare some further
patches tonight in this vein.
