Hi Mark,

I see a issue with one of the davinci boards, where regulator_get() fails
from this patch "regulator: core: Provide a dummy regulator with full
constraints".
as I see regulator_get() supports dummy regulators by default.

So currently I am booting it traditional way (NON DT way) and
regulator_dev_lookup()
fails (return NULL)  and for this check it fails.

+    if (ret && ret != -ENODEV) {
         regulator = ERR_PTR(ret);
         goto out;
     }
In the NON-DT case the 'ret' is never updated in regulator_dev_lookup().

I tried adding regulator_has_full_constraints(); call in .init_machine
but results
the same. Any pointer would be helpfull.

Thanks,
