Subject: [PATCH 02/15] aoe: add error handling support for add_disk()
Date: Mon, 30 Aug 2021 15:09:47 -0700	[thread overview]
Message-ID: <20210830221000.179369-3-mcgrof@kernel.org> (raw)
In-Reply-To: <20210830221000.179369-1-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.
