[PATCH] bluetooth/btusb.c: Add extra mediatek btusb target

[ultrabear]

From: Alexander Hall <bearodark@gmail.com>

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:

Bluetooth: btusb: Add USB HW id 0x3604 for MediaTek MT7925B22M

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].

You can amend the commit message with `git commit --amend`, and then do 
`git format-patch -v2` to get *v2* into the subject/title.

I am looking forward to more Linux contributions! ;-)


Kind regards,

Paul
