Please don't do things like this, it makes it harder to apply your
series. Just register all the devices in the MFD when you add the MFD
driver.

dev_warn().

Again, this looks like it should be generic.

This isn't adding anything, just remove it - the core already logs
probes if you want.

Are you sure this shouldn't be the MFD?

Why isn't this being read from the hardware, this may lead to a
configuration change the first time we pay attention?
