[PATCH] Bluetooth: btusb: Add USB ID 13d3:3631 for MediaTek MT7925

[Kenzi Voyer]

The Mercusys (TP-Link) MA37BE Wi-Fi/Bluetooth adapter uses a MediaTek
MT7925 chip whose Bluetooth part enumerates as USB ID 13d3:3631.
This ID is not present in the btusb device table, so the interfaces
bind without MediaTek driver data and HCI initialization fails with:

    Bluetooth: hci0: Opcode 0x0c03 failed: -16

leaving no usable Bluetooth controller. Adding the ID to the MT7925
section of the table makes the driver run the MediaTek setup path
(firmware load) and the adapter works normally afterwards.

Please disregard this patch.

As the CI bot notes, it no longer applies because drivers/bluetooth/btusb.c
has since been restructured. More importantly, Samuel Alhovuori already
submitted this same addition and his v2 was applied to bluetooth-next on
2026-09-08, so USB ID 13d3:3631 is already present in the current tree
(drivers/bluetooth/btusb_main.c).

Apologies for the duplicate submission and the noise.

Best regards,
Kenzi Voyer
