From c557a9ae4960a8aaede722833e567897f05aa9ef Mon Sep 17 00:00:00 2001 From: Minghao Chi Date: Wed, 13 Apr 2022 09:35:29 +0000 Subject: net: ethernet: ti: cpsw_new: use pm_runtime_resume_and_get() instead of pm_runtime_get_sync() Using pm_runtime_resume_and_get is more appropriate for simplifing code Reported-by: Zeal Robot Signed-off-by: Minghao Chi Signed-off-by: David S.
