From 860553023bfed0179b3fe5d01838635f54a314a3 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 6 Apr 2010 06:41:28 -0300 Subject: [PATCH] V4L/DVB: V4L2 Spec: fix V4L2_CTRL_TYPE_CTRL_CLASS documentation The spec says that the control ID for these types of controls is the same as that of the control class. But it should read: 'control class + 1'.
