We were only storing the report in case of QUIRK_MULTI_INPUT. It is interesting for the upcoming HID_QUIRK_INPUT_PER_APP to also store the full list of reports that are attached to it. We need the full list because a device (Advanced Silicon has some) might want to use a different report ID for the Input reports and the Output reports. Storing the full list allows the drivers to have all the data.
