[PATCH] USB: fix for HID field index
The problem I'm having is that the field index is always returned as 0
when reading struct hiddev_usage_ref and I need something to
distinguish the input data as the usage code is the same. I looked
through hid-core.c and hiddev.c and hiddev_hid_event is the only place
I could see field->index being used. It wasn't being initialized
causing the input to always be returned as zero.
