Let's not change the value of the other device-specific controls.

That's a bit of a long name. What about V4L2_CID_TEST_PATTERN_COLOR ?

I don't think this really requires a pr_warn(). I would just accept the value
without returning an error and write it to the MT9T001_TEST_DATA register. The
V4L2_CID_TEST_PATTERN control would then enable/disable the test pattern,
instead of storing the value in mt9t001->test_pattern.

No need to check that, just write the test pattern color to the
MT9V032_TEST_PATTERN_DATA field without changing the rest of the register. You
could also put the two test pattern controls in a cluster.
