[PATCH] net: dsa: mv88e6xxx: Add missing initialization in mv88e6xxx_set_port_state()

From: Geert Uytterhoeven
Date: Thu Apr 16 2015 - 14:49:21 EST


drivers/net/dsa/mv88e6xxx.c: In function âmv88e6xxx_set_port_stateâ:
drivers/net/dsa/mv88e6xxx.c:905: warning: âretâ may be used uninitialized in this function

If oldstate == state, mv88e6xxx_set_port_state() will return an
uninitialized value. Pre-initialize ret to zero to fix this.
