X-Git-Tag: v2.6.29-rc1~581^2~467
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b71e839f9a33abf8634b1eea4875bc8057fe39e2;p=pandora-kernel.git

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

this warning:

  drivers/net/cassini.c: In function ‘cas_rx_ringN’:
  drivers/net/cassini.c:2350: warning: ‘skb’ may be used uninitialized in this function

triggers because GCC does not recognize the (correct) error flow
between cas_rx_process_pkt() and 'skb'.

Annotate it.
