Ok, it looks like regulator_get will handle all things, looking forward
to your patches :)
Then I think my changes will be simple, just something like:
+ reg = devm_regulator_get(dev, "vcc");
+ if (!IS_ERR(reg)) {
+ err = regulator_enable(reg);
+ if (err < 0)
+ return err;
+ } else {
+ return PTR_ERR(reg);
+ }
Wei.
