Subject: [PATCH v2 06/10] nvdimm/btt: add error handling support for add_disk()
Date: Mon, 27 Sep 2021 15:00:35 -0700	[thread overview]
Message-ID: <20210927220039.1064193-7-mcgrof@kernel.org> (raw)
In-Reply-To: <20210927220039.1064193-1-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.
