[PATCH RESEND 0/4] regulator: debugging and fixing supply deps

[Michał Mirosław]

It turns out that commit aea6cb99703e ("regulator: resolve supply
after creating regulator") exposed a number of issues in regulator
initialization and introduced a memory leak of its own. One uncovered
problem was already fixed by cf1ad559a20d ("regulator: defer probe when
trying to get voltage from unresolved supply"). This series fixes the
remaining ones and adds a two debugging aids to help in the future.

The final patch adds a workaround to preexisting problem occurring with
regulators that have the same name as its supply_name. This worked
before by accident, so might be worth backporting. The error message is
left on purpose so that these configurations can be detected and fixed.

(The first two patches are resends from Nov 5).

(Series resent because of wrong arm-kernel ML address.)

Michał Mirosław (4):
  regulator: fix memory leak with repeated set_machine_constraints()
  regulator: debug early supply resolving
  regulator: avoid resolve_supply() infinite recursion
  regulator: workaround self-referent regulators
