From 8c7d3972fdbe9fb7644edea83e0ca5e771aa5563 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 2 Dec 2015 17:30:28 +0100 Subject: [PATCH] net: mpc52xx: Use platform_register/unregister_drivers() These new helpers simplify implementing multi-driver modules and properly handle failure to register one driver by unregistering all previously registered drivers.
