If you're saving 'i2c', do you really need to save the other two. You
can just derive them from the former.

This is a bool; true or false.

regmap_add_irq_chip() doesn't return >0, so check can simply be

Again, mfd_add_devices() can't return >0, so just check for 'ret'.

Should this driver depend on OF? If not, you need to use
of_match_ptr() here.
