Subject: [PATCH 01/14] block/swim3: add error handling support for add_disk()
Date: Fri,  3 Sep 2021 18:35:23 -0700	[thread overview]
Message-ID: <20210904013536.3181237-2-mcgrof@kernel.org> (raw)
In-Reply-To: <20210904013536.3181237-1-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.
