Subject: [PATCH 2/4] target_core_pscsi: use __scsi_device_lookup()
Date: Thu, 28 May 2020 10:42:25 +0200	[thread overview]
Message-ID: <20200528084227.122885-3-hare@suse.de> (raw)
In-Reply-To: <20200528084227.122885-1-hare@suse.de>

Instead of walking the list of devices manually use the helper
function to return the device directly.
