context.

- The video device is not allocated when mt9t031_init() is called, don't use
it in debug printk.

- The clock polarity is inverted in mt9t031_set_bus_param(), use the correct
one.

09e231b351 V4L/DVB (11024): soc-camera: separate S_FMT and S_CROP operations
As host and camera drivers become more complex, differences between S_FMT and
S_CROP functionality grow, this patch separates them.

aecde8b53b V4L/DVB (10141): v4l2: debugging API changed to match against driver name instead of ID.
Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.

Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.

Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

This camera is rather similar to MT9M001, but also has a couple of
enhanced features, like pixel binning.
