[PATCH 0/1] Bluetooth: btrtl: Add support for RTL8761B

[sztsian]

From: Zamir SUN <sztsian@gmail.com>

This patch adds support for the RTL8761B USB Bluetooth dongle.

When I got the RTL8761B dongle, I see it is actually recognised as
RTL8761A in my system (5.5.15-200.fc31.x86_64 on Fedora). And the
userspace cannot detect bluetooth devices in such situation.

[34691.248484] Bluetooth: hci0: command 0xfc20 tx timeout

With great help from Icenowy Zheng she helped identifying the firmware
from the vendor-provided Windows driver. After applying this patch along
with the firmware I am able to use this dongle.

Note, I don't have RTL8761A device, so I would appreciate if someone 
can help test in case this patch breaks RTL8761A.

Oh sorry, Self-NAK.
