From: Prarit Bhargava <prarit@redhat.com> Date: Thu, 27 May 2010 18:13:01 -0400 > Fix warning: > > drivers/net/bnx2.c: In function 'bnx2_disable_forced_2g5': > drivers/net/bnx2.c:1489: warning: 'bmcr' may be used uninitialized in this function > > Signed-off-by: Prarit Bhargava <prarit@redhat.com> This is another bad patch, you're hiding a bug by making this warning go away. If bnx2_read_phy() in fact does not initialize "bmcr" we might want to do something about that instead of just blindly using whatever garbage is in that local variable. Please stop making these patches without applying at least some intelligence to the analysis of why these warnings are being printed at all. None of these cases you're posting patches for are situations where the compiler simply can't see the control flow properly, they are real issues.
