Subject: [PATCH net-next-2.6] chelsio: Fix build warning.
Date: Tue, 13 Apr 2010 03:08:43 -0700 (PDT) [thread overview]
Message-ID: <20100413.030843.144389683.davem@davemloft.net> (raw)
GCC warns that:
drivers/net/chelsio/sge.c:463:11: warning: operation on 's->port' may be undefined
Better to eliminate the side effects in the calculation and
express what was intended here.
Signed-off-by: David S. Miller <davem@davemloft.net>
