Thanks for the report, @FiSh3rWoLf, and for the pre-submission sleuthing.

Curious we've not seen this one before. I'll need to check if this is specific to Raspberry Pi 5, or if it also affects the Raspberry Pi 4 family.

Applications need to use the blconfig alias and not hardcoded the rmem node https://github.com/raspberrypi/rpi-eeprom/blob/master/rpi-eeprom-update#L117
