From fb94d8f27fa8bd1491923b63152a38b296623b71 Mon Sep 17 00:00:00 2001 From: Cai Huoqing Date: Wed, 15 Sep 2021 22:57:41 +0800 Subject: [PATCH] net: arc_emac: Make use of the helper function dev_err_probe() When possible use dev_err_probe help to properly deal with the PROBE_DEFER error, the benefit is that DEFER issue will be logged in the devices_deferred debugfs file. And using dev_err_probe() can reduce code size, and simplify the code. Signed-off-by: Cai Huoqing Signed-off-by: David S.
