Dear Maintainer, On my Debian sid laptop, which has an AX201 chipset, I also confirmed the same bug as reported in this thread.
However, today Linux-image-5.15.0-2-amd64 came to sid. Then I installed this package right away, and I confirmed to resolve this bug. The AX201 Bluetooth on my laptop appeared to work entirely. Thank you for releasing the latest stable version of the kernel. -- Takahide Nojima
