The keyboard dock used with the Asus Transformer T100 series, uses the same vendor-defined 0xff31 usage-page as some other Asus keyboards. But with a small twist, it has a small descriptor bug which needs to be fixed up for things to work. This commit adds the USB-ID for this keyboard to the hid-asus driver and makes asus_report_fixup fix the descriptor issue, fixing various special function keys on this keyboard not working.
