From 0d81951dad5a0807277d2751ba2b4f98818b049d Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sat, 29 Aug 2020 08:47:25 +0200 Subject: [PATCH] iio: magnetometer: mag3110: Simplify with dev_err_probe() Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and also it prints the error value.
