* Fix FKB merging entities when MAC empty
Fully Kiosk Browser will sometimes return an empty MAC address in the
device_info API call. When two Fully Kiosk devices are added with
missing MAC addresses, HA will assume the two devices are the same and
merge the entities. This fixes that problem.
Fixes#77722
* Update homeassistant/components/fully_kiosk/entity.py
