X-Git-Tag: v3.2.94~60
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fd80d3feb67a7845cbed3df9557ae27ba3afe189;p=thirdparty%2Fkernel%2Fstable.git

scsi: bnx2i: missing error code in bnx2i_ep_connect()

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.")
