From 5f77af93266e107bd46c010c51d772c0fb003232 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Tue, 10 Mar 2009 13:06:40 -0300 Subject: [PATCH] V4L/DVB (10972): zl10353: i2c_gate_ctrl bug fix zl10353 i2c-gate was always closed and due to that devices having tuner behind i2c-gate were broken. Add module configuration which allows disabling i2c-gate only when really needed.
