Subject: [PATCH 9/9] media: docs: v4l2-controls: remove outdated paragraph
Date: Thu, 13 Jun 2019 16:18:26 +0200
Message-ID: <> (raw)
In-Reply-To: <>

This paragraph was added by commit a42b57f5aacf ("V4L/DVB: Documentation:
add v4l2-controls.txt documenting the new controls API") back in 2010, when
the controls API has been improved. Nowadays it is a bit anachronistic, so
remove it.

The same information is stated in up-to-date wording a few paragraphs later

> You’re done! And this is sufficient for most of the drivers we have. No
> need to do any validation of control values, or implement QUERYCTRL,
> are automatically supported.
