Subject: [PATCH] doc: media: v4l/func-open.rst: ENXIO should be ENODEV
Date: Fri, 23 Feb 2024 10:15:20 +0100	[thread overview]
Message-ID: <50346832-e726-4bb4-9f9b-375713afa5d5@xs4all.nl> (raw)

The error that V4L2 returns when an attempt is made to open an
unregisted device node is ENODEV, no ENXIO. Update the documentation.
