From 1e55126666944c83bf98243564e25302f363e2a4 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 8 Aug 2008 08:34:19 -0300 Subject: V4L/DVB (8637): v4l2: add v4l2_ctrl_query_menu_valid_items support function v4l2_ctrl_query_menu_valid_items() makes it easy to handle control menus that have a lot of invalid 'holes'. For example, many MPEG encoders only support a limited subset of audio bitrates. In that case a driver can specify an array listing the set of valid bitrates and pass that to this function.
