Hi,
something seems to be wrong with this two commits:
kernel: remove obsolete patch adding usb_find_device_by_name
ledtrig-usbdev: use upstream function for iterating USB devices
If a TP-Link WDR3600 or Archer-C7 router boots with a connected USB stick, this
error does
occur:

If the the WDR3600 boots without the USB stick and I connect it later, this
error doesn't
occur (not tested with the Archer-C7).
Regards,
Hartmut
