From 82d788750e35ab0bf7f5cc1005b694bb2ca3cf20 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Tue, 27 Sep 2022 15:26:15 +0800 Subject: usb: musb: jz4740: 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.
