Subject: [patch 27/36] Dereference in drivers/scsi/lpfc/lpfc_ct.c
Date: Tue, 10 Oct 2006 14:41:43 -0700	[thread overview]
Message-ID: <200610102141.k9ALfhAX025441@shell0.pdx.osdl.net> (raw)

From: Eric Sesterhenn <snakebyte@gmx.de>

If we fail to allocate mp->virt during the first while loop iteration,
mlist is still uninitialized, therefore we should check if before
dereferencing.
