From 23a456f05353035d1a2b3f1b9a92707acdc036e0 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Tue, 6 May 2014 18:52:16 +0200 Subject: [PATCH] net: mdio: of_mdiobus_register(): fall back to mdiobus_register() for !CONFIG_OF If CONFIG_OF is not set, make of_mdiobus_register() call mdiobus_register() instead of returning -ENOSYS. This way, we can just call of_mdiobus_register() from all DT-enabled drivers to handle the compat cases.
