Random whitespace change here.

Please don't abuse the ternery operator, write code as though people
were going to read it.

Are you *sure* you should be using regulator_bulk_get() here if you
never use the regulators en masse again?

Both empty?  It seems this CODEC does nothing so may as well not have a
driver...

Error checking.
