From 2c67521821acd900d7508f37e49d0b494011106d Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 12 Jul 2017 10:31:21 +0300 Subject: scsi: qedi: Fix return code in qedi_ep_connect() We shouldn't be writing over the "ret" variable. It means we return ERR_PTR(0) which is NULL and it results in a NULL dereference in the caller. Fixes: ace7f46ba5fd ("scsi: qedi: Add QLogic FastLinQ offload iSCSI driver framework.")
