  modprobe: ERROR: could not insert 'goodix': Unknown symbol in module, or unknown parameter (see dmesg)
  [   15.190397] goodix: Unknown symbol touchscreen_report_pos (err -2)
  [   15.221560] goodix: Unknown symbol touchscreen_parse_properties (err -2)
  [   64.677545] goodix: Unknown symbol touchscreen_report_pos (err -2)
  [   64.683767] goodix: Unknown symbol touchscreen_parse_properties (err -2)
