Does that patch actually fix anything? Does the kernel complain about the
missing vqmmc regulator?
I am asking because I wonder if we need this patch in the first place. The
generic MMC DT binding marks the vqmmc property as optional.

So I appreciate the idea of making everything neat and tidy, but after all
we have little actual proof that the voltage is really 3.3V, so I'd just
leave it as it is.

Cheers,
Andre
