V4L/DVB (11128): cx231xx: convert the calls to subdev format
Sri Deevi [Sat, 21 Mar 2009 02:33:48 +0000 (23:33 -0300)]
This patch converts cx231xx to the new v4l2 dev/subdev, doing:
 - Conversion of i2c calls to subdev calls;
 - all subdev calls to call_all();
 - Corrected the header file order in cx231xx.h;
 - Added tuner frequency setting.
