From 55e00b871ce2fc5689af7991638e5889dcd2ea7a Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Tue, 27 Sep 2022 14:48:41 +0800 Subject: iio: multiplexer: Switch to use dev_err_probe() helper In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs. It's more simple in error path.
