Subject: [PATCH] scsi: qla2xxx: check for kstrtol() failure
Date: Wed, 20 Feb 2019 05:39:13 +0000	[thread overview]
Message-ID: <20190220053913.GA25196@kadam> (raw)

The error handling was unintentionally left out so it introduces a
Smatch static checker warning:

    drivers/scsi/qla2xxx/qla_attr.c:1655 qla2x00_port_speed_store()
    error: uninitialized symbol 'type'.

Fixes: a7b9ca7fc87a ("scsi: qla2xxx: Add support for setting port speed")
