            Bug ID: 220815
           Summary: btusb: Add Realtek RTL8852CE device ID (13d3:3612)
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Bluetooth
          Assignee: linux-bluetooth@vger.kernel.org
          Reporter: azureller1@gmail.com
        Regression: No

The Realtek RTL8852CE combo WiFi/Bluetooth chip in the ASUS TUF Gaming A16
(2025) FA608 series laptops has a Bluetooth device that is not recognized as a
Realtek device by btusb, preventing btrtl from loading firmware.

Hardware Information:
- Laptop: ASUS TUF Gaming A16 FA608UP (2025)
- Bluetooth USB ID: 13d3:3612 (IMC Networks Bluetooth Radio)
- Chip: Realtek RTL8852CE
- WiFi works with rtw89 driver

lsusb output:
Bus 001 Device 002: ID 13d3:3612 IMC Networks Bluetooth Radio

Chip identification from btmon:
HCI version: Bluetooth 5.3 (0x0c) - Revision 12 (0x000c)
LMP version: Bluetooth 5.3 (0x0c) - Subversion 34898 (0x8852)
Manufacturer: Realtek Semiconductor Corporation (93)

Problem:
The USB ID 13d3:3612 is not in btusb's device table with BTUSB_REALTEK flag.
Without this flag, btusb handles the device generically and never calls btrtl.
The chip responds to HCI commands but the radio doesn't function because
firmware is never loaded.

Solution:
Add to drivers/bluetooth/btusb.c:
{ USB_DEVICE(0x13d3, 0x3612), .driver_info = BTUSB_REALTEK },

Tested on kernel 6.17.9-zen1-1-zen. After adding this line, btrtl loads
rtl8852cu_fw_v2.bin and Bluetooth works normally.
