bluetooth/btusb.c: Add extra mediatek btusb target

From: Alexander Hall <[email protected]>

This patch fixes bluetooth support on the MediaTek MT7925 WiFi 7 + BT 5.3 M.2 chipset that I purchased from aliexpress (and which arrived today). The PCB states that it is an MT7925B22M.

I tested that this patch did fix my problem; bluetooth now works.

The chipset was purchased from here, though the storefront image does not match the PCB that was recieved:

This is my first submitted patch to the linux kernel, apologies if I have misunderstood any portion of the process.

Dear Alexander,

Thank you for the patch, and welcome to the Linux kernel!

Fore the summary, I’d use:

Maybe save on archive.org and reference that.

Please also add the output of /sys/kernel/debug/usb/devices to the commit message as done in other commits (git log drivers/bluetooth/btusb.c).

Welcome! For this subsystem, your patch is going to be checked by a bot. It will probably ask you to use Bluetooth: as the prefix. Also, you should Cc: the maintainers. It can be integrated in git [1].
