From 1d32a62c74b3bcb69822b0f4745af5410cfec3a7 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 23 Jun 2017 10:02:00 +0300 Subject: [PATCH] scsi: bnx2i: missing error code in bnx2i_ep_connect() If bnx2i_map_ep_dbell_regs() then we accidentally return NULL instead of an error pointer. It results in a NULL dereference in iscsi_if_ep_connect(). Fixes: cf4e6363859d ("[SCSI] bnx2i: Add bnx2i iSCSI driver.")
