I think the change is OK, the commit log isn't optimal though.

You might want to point out that the problem only occurs if the driver
is built-in and that mc13783_regulator_probe doesn't need to be changed
as it already lives in .devinit.text

As if mc13783-regulator is built-in mc13783-core is built-in, too, the
wording isn't good.  The problem is (I suppose) that regulators are
linked first and so mc13783-core isn't *probed* early enough and so the
mc13783-regulator device isn't available at mc13783-regulator probing
