HID: input: rework HID_QUIRK_MULTI_INPUT
The purpose of HID_QUIRK_MULTI_INPUT is to have an input device per report id. This is useful when the HID device presents several HID collections of different device types. The current implementation of hid-input creates one input node per id per type (input or output). This is problematic for the LEDs of a keyboard as they are often set through an output report. The current code creates one input node with all the keyboard keys, and one other with only the LEDs. To solve this, we use a two-passes way: - first, we initialize all input nodes and associate one per report id - then, we register all the input nodes Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
