6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Max Chou <max.chou@xxxxxxxxxxx>
commit bd003fb338afee97c76f13c3e9144a7e4ad37179 upstream.
In this commit, prefer to load FW v2 if available. Fallback to FW v1
otherwise. This behavior is only for RTL8852C.
Fixes: 9a24ce5e29b1 ("Bluetooth: btrtl: Firmware format v2 support")
