Subject: [PATCH] IX2505V Keep I2C gate control alive.
Date: Fri, 22 Apr 2011 10:00:22 +0100 [thread overview]
Message-ID: <1303462822.2525.2.camel@localhost> (raw)
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.
