Product: Drivers
Version: 2.5
Kernel Version: 5.9.12 mainline
Hardware: All

Hi,
The bluetooth with device rtl8822cu does not work with 5.9.12 mainline kernel
(and all 5.9 kernel).
Before it worked fine with 5.8.0 mainline kernel.
A similar problem was solved for rl8822ce in 5.9.11 kernel by arch.
Discussion here : https://bbs.archlinux.org/viewtopic.php?pid=1940003#p1940003
I'm new here, so let me know what attachment you need.
Thank you.
