Hi, I have a small USB dongle for combined Wifi and Bluetooth. It’s based on the rtl8723b chip. Until recently it worked flawlessly (I never used Wifi, but Bluetooth worked). But now I can’t connect to paired devices and when scanning for new devices the adapter doesn’t find anything.
I did sudo dmesg |grep -i bluetooth and it retured this:

The line Direct firmware load for rtl_bt/rtl8723b_config.bin failed with error -2 seemed interesting and after some digging around I found this patch.
I’m currently on kernel 5.17.1-3-MANJARO using Gnome 41.5.
Does someone know a fix for this or do I have to wait for this patch to get merged?
Btw. I’m open to all feedback and if you need more information just ask
