Bluetooth driver error on boot after upgrade to bookworm

[Unni <unnimailinglist@gmail.com>]

Hello,

I am getting Bluetooth firmware error after upgrade. I've tried 
reinstalling firmware-iwlwifi. But no luck. I've added non-free-firmware 
in apt source, so thats not the issue. Help me to fix the error on booth.
