The dmesg file with 5.3.0-rc6 kernel
We have a laptop equipped with Intel i3-10110U CPU and Realtek 8822CE WiFi/BT
combo chip.
I have tested with 5.3.0-rc6 mainline kernel and the firmware from the commits:
aa703aad295d rtl_bt: Update RTL8822C BT FW to V0x098A_94A4
7e431c5dee00 rtw88: RTL8822C: add WoW firmware v7.3
2dc7023fd529 rtw88: RTL8822C: update rtw8822c_fw.bin to v7.3
However, system cannot discover any pair-able BT device. For example, our
"pulse" BT headset, which can be discovered and paired on other laptops.
