Subject: [PATCH] bnx2x: fix mem leak when command is unknown
Date: Tue, 31 Jul 2012 23:39:37 +0200 (CEST) [thread overview]
Message-ID: <alpine.LNX.2.00.1207312337590.7100@swampdragon.chaosbits.net> (raw)
In bnx2x_mcast_enqueue_cmd() we'll leak the memory allocated to
'new_cmd' if we hit the deafault case of the 'switch (cmd)'.
Add a 'kfree(new_cmd)' to that case to avoid the leak.
