From 053e7e169229adebbc27fc176c5369398e9f5eba Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 6 Jan 2016 20:11:12 +0100 Subject: [PATCH] phy: phy_{read|write}_mmd_indirect: get addr from phydev The address of the device can be determined from the phydev structure, rather than passing it as a parameter.
