From 2d79af6e35cd93614560b5b7e760daa306978813 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 15 Aug 2016 17:18:57 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: rename _mv88e6xxx_wait Now that there is no locked version of the wait routine anymore, rename the _ prefixed version and make it use the new read API.
