Comment 4 for bug 1954300

While the two kernel patches cannot be cleanly backported, I pushed version 5.14.0-9010.10+staging.34 to https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/intermediate-kernel that includes them. Need verification because mainline MTK bluetooth driver has changed a lot, and there might be other prerequisite fixes to be discovered.

Firmware part is being SRUed and is included in version 1.187.23+staging.37 from https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/linux-firmware-staging at the same time.
