FYI: 8852AE (Thinkapd P14s Gen2 AMD) Issues and Fixes #3

Sorry, not a real issue, but this information belongs in this repo:

The 8852AE caused nothing but trouble with BT headsets. The constant buffer underruns when using mSBC made it basically useless, forcing me to buy a USB BT dongle.

Using this driver fixed this issue, although toggling BT on and off completely knocked out the driver, breaking Bluetooth altogether, forcing a reboot (haven't tried unloading, and reloading the module).

Somewhere with Linux 5.18 (5.18.15?, sorry no time to bisect), however, all issues this was resolved(at least when adding iommu=pt to the kernel cmdline).

Sorry for the low quality info, but I really do not have the time to investigate ATM.
