OK, will remove it.

OK, will update.

Yes, can remove it.

Yes, maybe you are right, we misunderstood this usage.
But I'm confused with how can we put the sensor module name to upper level?
I mean upper level user want to know which sensor module is connecting to the controller.
Currently, our user get the sensor module name by call this ioctl VIDIOC_QUERYCAP.
Anyway, maybe we need change the usage model.
