From 56e31bd89334325f918e4b9f4d91f07157400169 Mon Sep 17 00:00:00 2001 From: Ivan Khoronzhuk Date: Wed, 10 Aug 2016 02:22:38 +0300 Subject: [PATCH] net: ethernet: ti: cpsw: replace pdev on dev No need to hold pdev link when only dev is needed. This allows to simplify a bunch of cpsw->pdev->dev now and farther. Signed-off-by: Ivan Khoronzhuk Reviewed-by: Mugunthan V N Signed-off-by: David S.
