From 411c4597df7dcc60b7aae83761618c94a60ded3f Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Thu, 22 Sep 2022 21:33:23 +0800 Subject: [PATCH] USB: PHY: JZ4770: 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.
