Subject: dsa: fix warning in net/dsa/mv88e6060.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d3f644da909549a4cf0ad27541df342f75158cc0;p=linux-beck.git

dsa: fix warning in net/dsa/mv88e6060.c

this warning:

  net/dsa/mv88e6060.c: In function ‘mv88e6060_poll_link’:
  net/dsa/mv88e6060.c:225: 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.
