Hello Dmitry.

Couple things actually:
o Could you please update the MAINTAINER entry for
BNX2X? Ariel Elior's email address is still listed
as @broadcom and that seems to bounce.

o I found this via coccinelle actually.
Julia Lawall submitted a patch to remove unused
netdev_priv calls. I modified that to check for
any expression that returns an unused value and
found this and many others. There are a lot of
false positives though.

local idexpression x;
expression E;
@@
-x = E;
... when != x
