Subject: [PULL v2 70/86] virtio: drop name parameter for virtio_init()
Date: Mon, 16 May 2022 16:54:56 -0400	[thread overview]
Message-ID: <20220516204913.542894-71-mst@redhat.com> (raw)
In-Reply-To: <20220516204913.542894-1-mst@redhat.com>

From: Jonah Palmer <jonah.palmer@oracle.com>

This patch drops the name parameter for the virtio_init function.

The pair between the numeric device ID and the string device ID
(name) of a virtio device already exists, but not in a way that
lets us map between them.

This patch lets us do this and removes the need for the name
parameter in the virtio_init function.
