From bd003fb338afee97c76f13c3e9144a7e4ad37179 Mon Sep 17 00:00:00 2001 From: Max Chou max.chou@realtek.com Date: Mon, 7 Aug 2023 19:42:59 +0800 Subject: [PATCH] Bluetooth: btrtl: Load FW v2 otherwise FW v1 for RTL8852C

In this commit, prefer to load FW v2 if available. Fallback to FW v1 otherwise. This behavior is only for RTL8852C.
