I wonder about unintended consequence related to the
notices:

regulator: shutting down unused regulators
regulator: shutting down cam-dummy-reg... ok

Also I wonder about use of uninitialized memory that might be
sensitive to very detailed build differences for what is seen
for the uninitialized value(s).

Not that I have any specific evidence of either.
