The necessary firmware will be submitted to linux-firmware project. Note that the Bluetooth devices WITH the VID=0x0bda would be set the feature quirk in btrtl_setup_realtek(). It's able to ignore the feature flag set for the specific VID and PID in blacklist_table[] of btusb.c. (check [1]) If Realtek Bluetooth chips WITHOUT the VID=0x0bda, it shall be added the feature flag for the specific VID and PID in blacklist_table[] of btusb.c.
