Some devices may not support specific type of input devices. For example,
when a headset or extension cable with GND/MIC swap is plugged into a
headset jack that does not support the headset/cable, it needs to be
reported with a corresponding input event. Also, increase the max values
for INPUT_DEVICE_ID_SW_MAX and SW_MAX, to accommodate future extension of
the number of event.

I do not think that adding this switch is a good idea as it will not
allow you to easily extend the reporting and to convey to the user why
something is not supported. I would look into alternate mechanism to
signal when and why a headset/peripheral was rejected.

Thanks.
