Subject: [Patch] Dereference in drivers/scsi/lpfc/lpfc_ct.c
Date: Sun, 01 Oct 2006 22:31:46 +0200	[thread overview]
Message-ID: <1159734706.11887.6.camel@alice> (raw)

hi,

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