Detected that integration 'ipp' passes a non-string value of type list as sw_version to the device registry at homeassistant/components/ipp/sensor.py, line 126: async_add_entities(sensors, True).

It looks like the printer returns multiple values for the software version, or the ipp lib doesn't parse it correct 🤔
