[PATCH 02/10] HID: hid-input: add usage_index argument in input_mapping and event.

From: Benjamin Tissoires
Date: Thu Oct 25 2012 - 10:14:02 EST

Currently, there is no way to know the index of the current field
in the .input_mapping and .event callbacks when this field is inside
an array of HID fields.
This patch transfers this index to the input_mapping and event
callbacks.
