If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

Hi,

I'm not sure that this one makes a real sense for backport.

It can't hurt, but it does not fix a real issue, it just voids a potential spurious message.

In my original mail, there is no "stable@" or "fix" or "bug" keywords or "Fixes:" tag. There is also apparently no patch in this backport serie that relies on this patch.

Why has it been selected?

(same for 5.15 and 5.19)

commit d20abd39a7843f50e07b6487c205d775f3361ac1 Author: Christophe JAILLET christophe.jaillet@wanadoo.fr Date: Wed Aug 17 15:04:00 2022 +0200

 hwmon: (pmbus) Use dev_err_probe() to filter -EPROBE_DEFER error messages
 
 [ 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.
