rainbow migration script for TOS 5->6 on Turris 1.x could create an invalid config in some cases
The rainbow migration script for Turris 1.x could create an invalid configuration if lan* LEDs were set. These LED names were migrated to lan-<num>
instead of the correct lan_<num>
and UCI has issues with handling -
in LED names. This broke anything that tried to access the rainbow uci entries including rainbow.
