Subject: [PATCH AUTOSEL 5.12 02/33] regulator: max77620: Silence deferred probe error

From: Dmitry Osipenko <digetx@...il.com>

[ Upstream commit 62499a94ce5b9a41047dbadaad885347b1176079 ]

One of previous changes to regulator core causes PMIC regulators to
re-probe until supply regulator is registered. Silence noisy error
message about the deferred probe.
