From 7740ab84c13e32002742106afd443a4ca7fe3918 Mon Sep 17 00:00:00 2001 From: Rouven Czerwinski Date: Wed, 16 Jun 2021 14:53:31 +0200 Subject: [PATCH] regulator: fixed: use dev_err_probe for gpio Instead of returning the the PTR_ERR directly, use dev_err_probe which will also correctly set the deferred probe reason in /sys/kernel/debug/deferred_devices, making it easier to debug missing devices on the system.
