Subject: [PATCH 0/2] rust: regulator: relax a few constraints on
 Regulator<T>

This series implement two related changes to address a bit of an oversight
on my end on the initial patch for the Regulator abstraction. Note that
this is not a fix, as it just relaxes the constraints on the previous code
as it is safe to do so.

Patch 1 removes some needless &mut self for functions that already provide
their own locking on the C side.

Patch 2 implements Send and Sync. In particular, there is no reason for
Regulator<T> not to be Send, and as discussed above, it is naturally Sync.

This is based on linux-next for now, I am waiting for 6.17-rc1 to be out in
order to rebase.
