The message means that a sysfs path was registered twice for some reason; either from a driver registering it twice, or from two drivers trying to register the same name.

  • Are you using the mainline kernel, or a distribution kernel, or perhaps a Freescale image? – Stephen Kitt Feb 19 '20 at 19:38
  • mainline, debian 10 buster – printf Feb 19 '20 at 19:38
