Please don't - the fix is completely broken for multi-input devices - if 2nd device fails to register we bail out of hidinput_connect and thus never set HID_CLAIMED_INPUT bit. So when we disconnect device we never call hidinput_disconnect and who knows what will happen after that. hidinput_connect() should properly unwind already registered devices after failure. -- Dmitry
