I copied this function from hid/hid-sensor-hub.c as it is marked
static in that file. I use it to fill attributes as I find them.
Should I create an another patch to make it non-static?

This is how I mange to find all possible hid reports in the parse
reports function. I noticed that in the other function that was used,
sensor_hub_input_get_attribute_info(),  it only uses field->usage[0].
Is there a reason for this and should I change my current
implementation?
