Subject: [PATCH net-next-2.6] bnx2: avoid compiler warnings
Date: Tue, 03 Nov 2009 10:17:42 +0100 [thread overview]
Message-ID: <4AEFF536.1020402@gmail.com> (raw)
drivers/net/bnx2.c: In function ‘bnx2_enable_forced_2g5’:
drivers/net/bnx2.c:1447: warning: ‘bmcr’ may be used uninitialized in this function
drivers/net/bnx2.c: In function ‘bnx2_disable_forced_2g5’:
drivers/net/bnx2.c:1482: warning: ‘bmcr’ may be used uninitialized in this function
One fix would be to have an initial value, but a plain return might be better.
