Subject: [PATCH 07/10] block/sunvdc: add error handling support for add_disk()
Date: Wed,  1 Sep 2021 14:00:25 -0700	[thread overview]
Message-ID: <20210901210028.1750956-8-mcgrof@kernel.org> (raw)
In-Reply-To: <20210901210028.1750956-1-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.

We re-use the same free tag call, so we also add a label for
that as well.
