From 75e13a76bf2af7ad890038e9de7235c42a3e5fa6 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sat, 29 Aug 2020 08:47:21 +0200 Subject: [PATCH] iio: imu: inv_mpu6050: 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.
