The RTL8761AU Bluetooth controller functions correctly but there is an error
like below in dmesg because the rtl8761a_config.bin config file is missing.
[ 171.949697] bluetooth hci0: Direct firmware load for rtl_bt/rtl8761a_config.bin failed with error -2
To suppress this error message, add a soft link from rtl8761a_config.bin to
rtl8761bu_config.bin. The latter is an empty/header-only config file
compatible with this device.
