3.2.94-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 1d32a62c74b3bcb69822b0f4745af5410cfec3a7 upstream.
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.")
