Hi,

Commit 044014ce85a1 ("Bluetooth: btrtl: Add Realtek devcoredump support")
broke Realtek-based ASUS USB-BT500, ID 0b05:190e.

Devices failed to connect. hciconfig showed a controller with all-zero BD
address.

I reverted the commit as well as bd003fb338af that depends on the commit.
It made the problem go away.

I know virtually nothing about bluetooth. Let me know what info you need
to debug the issue.
