well, if it no lna regulator is defined in the dtb, the regulator
framework will return a dummy regulator. devm_regulator_get_optional()
would not do that and would require more error checking in the code.
But if there is some rule which says that devm_regulator_get_optional()
should be used here, I can of course change that.
Before sending a v2, is that the only issue here?
