commit 276559d8d02c2709281578976ca2f53bc62063d4 upstream.
Valid HID_GENERIC type of devices set EV_KEY and EV_ABS by wacom_map_usage. When *_input_capabilities are reached, those devices should already have their proper EV_* set. EV_KEY and EV_ABS only need to be set for non-HID_GENERIC type of devices in *_input_capabilities.
Devices that don't support HID descitoprs will pass back to hid-input for registration without being accidentally rejected by the introduction of patch: "Input: refuse to register absolute devices without absinfo"
