From 8c7cb12ac1cc4ecc318765e0e2dcd853fa4a4d62 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 11 May 2012 09:07:45 -0300 Subject: [PATCH] [media] cx88: each device node gets the right controls radio only sees audio controls, video sees video and audio and vbi sees none. Also disable the chroma_agc control if secam is selected.
