Subject: [PATCH] hwmon: (pmbus) Use dev_err_probe() to filter -EPROBE_DEFER error messages
Date: Wed, 17 Aug 2022 15:04:00 +0200	[thread overview]
Message-ID: <3adf1cea6e32e54c0f71f4604b4e98d992beaa71.1660741419.git.christophe.jaillet@wanadoo.fr> (raw)

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.
