Good old gcc 4.1.2 (which I still use for m68k builds, and won't retire anytime
soon as it finds real bugs in every new kernel release) says:
drivers/net/dsa/mv88e6xxx.c: In function ‘mv88e6xxx_set_port_state’:
drivers/net/dsa/mv88e6xxx.c:905: warning: ‘ret’ may be used
uninitialized in this function
Even after your patch, as it missed one case (patch sent).
