From 853e3b2930001534b88fb36e936c9a734a79046c Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Fri, 22 Apr 2011 06:00:22 -0300 Subject: [PATCH] [media] IX2505V Keep I2C gate control alive Gate could close after first I2C message. On stv0288 it does. Keep 2nd and 3rd message I2C gate control alive. Remove unnecessary gate closing in this module.
