This does not compile.

You're not holding imx334->mutex here, as you should. Also accessing
imx334->cur_code should only be done while that mutex is acquired.

What's the purpose of calling __v4l2_ctrl_modify_range() here, all these
values are static once probe() function has been called, aren't they?

I'm dropping this patch for now, taking the first four.
