[ Upstream commit a8b38d19857d42a1f2e90c9d9b0f74de2500acd7 ]

The new platform uses the QCA2066 chip along with a new board ID, which
requires a dedicated firmware file to ensure proper initialization.
Without this entry, the driver cannot locate and load the correct
firmware, resulting in Bluetooth bring-up failure.

This patch adds a new entry to the firmware table for QCA2066 so that
the driver can correctly identify the board ID and load the appropriate
firmware from 'qca/QCA2066/' in the linux-firmware repository.

## Commit Analysis: Bluetooth: btusb: Add new VID/PID 0x0489/0xE12F for
RTL8852BE-VT

### 1. COMMIT MESSAGE ANALYSIS

- **Subject**: Adding a new USB Vendor/Product ID for a Realtek
  Bluetooth chip variant
- **No "Cc: stable@vger.kernel.org"** tag present
- **No "Fixes:"** tag present
- Commit message includes detailed device info from
  `/sys/kernel/debug/usb/devices`, confirming this is real hardware
  that's been tested
- Signed off by Realtek engineer (the hardware vendor) and Bluetooth
  maintainer

### 2. CODE CHANGE ANALYSIS

The diff is extremely simple:
```c
+       { USB_DEVICE(0x0489, 0xe12f), .driver_info = BTUSB_REALTEK |
+
BTUSB_WIDEBAND_SPEECH },
```

- **2 lines added** to the `quirks_table[]` static array
- Uses identical `driver_info` flags as the existing RTL8852BE-VT entry
  (`0x0bda, 0x8520`)
- Placed in the appropriate "Realtek 8852BT/8852BE-VT Bluetooth devices"
  section
- No code logic changes whatsoever - just adding an entry to a USB
  device ID table

### 3. CLASSIFICATION

This falls squarely under the **NEW DEVICE IDs** exception, which is
explicitly allowed in stable:

> "Adding PCI IDs, USB IDs, ACPI IDs, etc. to existing drivers - These
are trivial one-line additions that enable hardware support"

This is **not** a new feature. The btusb driver already fully supports
RTL8852BE-VT devices. This simply registers another VID/PID combination
for the same chipset.

### 4. SCOPE AND RISK ASSESSMENT

| Factor | Assessment |
|--------|------------|
| Lines changed | 2 (minimal) |
| Files touched | 1 (`drivers/bluetooth/btusb.c`) |
| Complexity | Trivial - static table entry |
| Risk | **Extremely low** |

- Change only affects devices matching VID 0x0489 / PID 0xe12f
- Cannot regress any existing functionality
- No behavioral changes to the driver code itself

### 5. USER IMPACT

- **Without this patch**: Users with this Bluetooth adapter have non-
  functional hardware
- **With this patch**: The adapter is recognized and works with existing
  Realtek support
- **Severity for affected users**: High - complete loss of Bluetooth
  functionality
- This is a real Realtek product (vendor confirmed via signoff)

### 6. STABILITY INDICATORS

- Submitted by Realtek engineer (Max Chou) - hardware vendor
- Merged by Bluetooth maintainer (Luiz von Dentz)
- Device info in commit message demonstrates the device exists and was
  tested

### 7. DEPENDENCY CHECK

- No dependencies on other commits
- The btusb driver with Realtek support (`BTUSB_REALTEK`) exists in all
  stable trees
- `BTUSB_WIDEBAND_SPEECH` flag is also well-established

---

## Summary

This is a textbook example of a commit that should be backported to
stable:

**Benefits**:
- Enables real hardware for real users
- Zero risk of regression (only affects specific VID/PID)
- Trivial 2-line data table addition
- Obviously correct - follows exact same pattern as dozens of other
  entries
- Hardware vendor submitted the patch

**Concerns**:
- No explicit stable tags (common for device ID additions; maintainers
  often omit these for routine changes)

The absence of `Cc: stable` is not concerning for device ID additions -
they're so routine that many maintainers don't bother tagging them, yet
stable maintainers regularly pick them up. This enables users with this
Bluetooth adapter to have working hardware on stable kernels without
requiring a full kernel upgrade.

**YES**
