Subject: [PATCH 5.15 16/35] hwmon: (pmbus) Use dev_err_probe() to filter -EPROBE_DEFER error messages

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 09e52d17b72d3a4bf6951a90ccd8c97fae04e5cf ]

devm_regulator_register() can return -EPROBE_DEFER, so better use
dev_err_probe() instead of dev_err(), it is less verbose in such a case.

It is also more informative, which can't hurt.
