I've recently bought the new [2022 Razer Blade 14'' with 3070
Ti](https://mysupport.razer.com/app/answers/detail/a_id/5924/~/at-a-
glance%3A-razer-blade-14-%282022%29-%7C-rz09-0427x).
Unfortunately after installing Ubuntu 22.04 Desktop I've quickly come to
realize that neither WiFi nor BT are working.

Can anyone help me with resolving this issue?
Edit: I tried Ubuntu 18.x, 20.x, 21.x, 22.x and fedora 36 with all
various kernels and it all shows the same errors. Looks like only
Windows has the drivers for the recent hardware.

Bug description:
[Impact]
Qualcomm WCN6856 doens't work.
[Fix]
Backport missing bits to make Wifi 5 work. Wifi 6 support is not in the
scope of this SRU.
[Test]
The system can connect to Wifi. Wifi still works after several rounds of
suspend/resume cycles.
[Where problems could occur]
The change is limited to ath11k, which is also the only user of mhi bus,
so the scope of risk is limited. Let alone it never worked before, so
there's not much room to go wrong.
