From 098cbc38c27dee66e5bc7f088c30b96e5cc96510 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 24 Mar 2013 06:09:29 -0300 Subject: [media] DocBook/media/v4l: remove the documentation of the obsolete dv_preset API This API is no longer used by any driver and so can be removed from the documentation.
