[PATCH 1/2] HID: add hid_type

From: Jiri Slaby
Date: Sun Oct 19 2008 - 10:16:21 EST


Add type to the hid structure to distinguish to which device type
(mouse/kbd) we are talking to. Needed for per device type ignore
list support.

Note: this patch leaves the type as unknown for bluetooth devices,
there is not support for this in the hidp code.
