Subject: [PATCH 06/10] block/rsxx: add error handling support for add_disk()
Date: Wed, 1 Sep 2021 14:00:24 -0700 [thread overview]
Message-ID: <20210901210028.1750956-7-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.
