From 058112c7efc9ef43bb511c137293dddbe6e42908 Mon Sep 17 00:00:00 2001 From: Sebastian Hesselbarth Date: Mon, 6 May 2013 23:49:31 +0000 Subject: net: of_mdio: fix behavior on missing phy device of_mdiobus_register creates a phy_device even if get_phy_device failed to create it previously. This causes indefinite polling on non-existent PHYs. This fix makes of_mdio_register rely on get_phy_device to properly create the device or fail otherwise.
