From 68fffc191ed19ea5618285b128e6048d1536e680 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 1 Sep 2020 17:27:12 +0200 Subject: [PATCH] spi: tegra114: Simplify with dev_err_probe() Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and the error value gets printed.
