Subject: [PATCH 10/10] mtd/ubi/block: add error handling support for add_disk()
Date: Wed,  1 Sep 2021 14:00:28 -0700	[thread overview]
Message-ID: <20210901210028.1750956-11-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.
