lscpi, lsusb and dmesg output

Bluetooth stopped working after switching to kernel 5.9, it still works if I
boot kernel 5.8 again.

Hardware:
Lenovo IdeaPad5 14are05
Realtek Semiconductor Co., Ltd. RTL8822CE 802.11ac PCIe Wireless Network
Adapter
with integrated Bluetooth 2.1/3.0/4.2 USB interface controller

bluetoothhctl list doesn't show the controller

lsusb -v shows a Realtek Bluetooth Radio controller.

lspci -vv show also the Realtek Wireless Network Adapter.
