Subject: s2io: fix warning in drivers/net/s2io.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2e6a684b8489b21324f314be2bd8d3788a9f6445;p=linux-beck.git

s2io: fix warning in drivers/net/s2io.c

this warning:

  drivers/net/s2io.c: In function ‘rx_intr_handler’:
  drivers/net/s2io.c:7369: warning: ‘lro’ may be used uninitialized in this function

triggers because GCC does not recognize the (correct) error flow
between:

 - s2io_club_tcp_session()and 'lro'

Annotate it.
