[    1.510000] platform-lcd supply lcd_vdd not found, using dummy regulator

I was sorta hoping that there would be some magic where
regulator_get() would find the device tree node for the regulator and
then resolve the chain.  ...but maybe that's a pipe dream.

You shouldn't have dummy regulators enabled at all, that'll break a
bunch of stuff including dependency resolution.  They're a crutch to
help get things booting not something you should be using in production.
If they're not enabled regulator_get() will defer the probe.
