Voltage regulators are needed very early due to deferred probe
being incompatible with built-in USB gadget drivers.
What does it need to fix those instead?

Discussion on that topic came about from this submission:

We can either add to the many drivers that already do subsys_initcall()
for similar reasons...or I can drop this from the series and add gadget
probe ordering to my TODO list.
In short, it can't be a late_initcall() hack like the original post and
really could be solved by converting to a real bus (and letting
deferred probe do its job)..but Alan voiced concerns about that.
Don't worry too much about what I said. If adding a "gadget" bus will
solve the problem in an appropriate way, and if nobody else objects
(particularly Felipe, who is on vacation now), then go for it.
Ok, I'll take a look at what can be done and restart the conversation
when Felipe returns.
Wolfram: given this, as I mentioned, I'll simply drop this patch from
the series and work around it for now. This will probably make Lee and
Mark happy to not see subsys_initcall() in the MFD/regulator drivers as
well.
