Subject: [PATCH 10/11] virtio_blk: add error handling support for add_disk()
Date: Wed, 18 Aug 2021 16:45:41 +0200	[thread overview]
Message-ID: <20210818144542.19305-11-hch@lst.de> (raw)
In-Reply-To: <20210818144542.19305-1-hch@lst.de>

From: Luis Chamberlain <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.
