From 6d07a68a59274fa168a3ddfbcfe5df029ba0afed Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 15 May 2018 16:56:18 -0700 Subject: of: mdio: Fall back to mdiobus_register() with NULL device_node When the device_node specified is NULL, fall back to mdiobus_register(). We have a number of drivers having a similar pattern which is: if (np) of_mdiobus_register() else mdiobus_register() so incorporate that behavior within the core of_mdiobus_register() function. This is also consistent with the stub version that we defined when CONFIG_OF=n. Signed-off-by: Florian Fainelli Signed-off-by: David S.
