dsa: fix warning in net/dsa/mv88e6xxx.c
this warning: net/dsa/mv88e6xxx.c: In function ‘mv88e6xxx_poll_link’: net/dsa/mv88e6xxx.c:361: warning: ‘port_status’ may be used uninitialized in this function triggers because GCC does not recognize the (correct) error flow between 'link' and 'port_status'. Annotate it. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: David S. Miller <davem@davemloft.net>
