This won't work. Setting the V4L2_CID_TEST_PATTERN_COLOR control will disable
the test pattern, and setting the V4L2_CID_TEST_PATTERN control will set the
color to 0. You should put the two controls in a cluster. You can have a look
at how the mt9m032 driver handles the horizontal and vertical flip controls
for sample code.
