net: mscc: ocelot: Fix uninitialized error in ocelot_netdevice_event()
With gcc-4.1.2:
drivers/net/ethernet/mscc/ocelot.c: In function ‘ocelot_netdevice_event’:
drivers/net/ethernet/mscc/ocelot.c:1129: warning: ‘ret’ may be used uninitialized in this function
If the list iterated over by netdev_for_each_lower_dev() is empty, ret
is never initialized, and converted into a notifier return value.
Fix this by preinitializing ret to zero.
Fixes: a556c76adc052c97 ("net: mscc: Add initial Ocelot switch support")
