Subject: [PATCH v2 01/14] block/swim3: add error handling support for add_disk()
Date: Mon, 27 Sep 2021 15:02:49 -0700 [thread overview]
Message-ID: <20210927220302.1073499-2-mcgrof@kernel.org> (raw)
In-Reply-To: <20210927220302.1073499-1-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.
