Subject: [dm-devel] [PATCH v2 2/6] scsi/sr: add error handling support for add_disk()
Date: Fri, 27 Aug 2021 12:05:00 -0700	[thread overview]
Message-ID: <20210827190504.3103362-3-mcgrof@kernel.org> (raw)
In-Reply-To: <20210827190504.3103362-1-mcgrof@kernel.org>

We never checked for errors on add_disk() as this function
returned void. Now that this is fixed, use the shiny new
error handling.
