[ 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.

## Analysis: Bluetooth: btusb: MT7922: Add VID/PID 0489/e170
### 1. COMMIT MESSAGE ANALYSIS
**Subject**: Adding a new USB Vendor ID (VID) 0x0489 and Product ID
(PID) 0xe170 for a MediaTek MT7922 Bluetooth chip.
**Key Tags**:
- Signed-off-by: Chris Lu from MediaTek (the chip vendor)
- Reviewed-by: Paul Menzel
- Signed-off-by: Luiz Augusto von Dentz (Bluetooth maintainer)
No explicit `Cc: stable@vger.kernel.org` tag, but this is common for
device ID additions which are often handled implicitly.
### 2. CODE CHANGE ANALYSIS
The change is a 2-line addition to the `quirks_table[]` array:
```c
{ USB_DEVICE(0x0489, 0xe170), .driver_info = BTUSB_MEDIATEK |
BTUSB_WIDEBAND_SPEECH },
```
This simply registers a new USB device ID with existing driver flags
(`BTUSB_MEDIATEK` and `BTUSB_WIDEBAND_SPEECH`) that are already fully
supported. The btusb driver already contains full MT7922 support - this
just adds another VID/PID variant to the recognition table.
### 3. CLASSIFICATION
This is a **NEW DEVICE ID** addition - one of the explicitly allowed
exception categories for stable backports:
- Adding a USB VID/PID to an existing, well-tested driver
- Trivial one-entry addition to a device table
- The driver code for MT7922 already exists; only recognition is missing
### 4. SCOPE AND RISK ASSESSMENT
| Metric | Assessment |
|--------|------------|
| Lines changed | 2 |
| Files touched | 1 |
| Complexity | Minimal - static table entry |
| Risk | **Extremely low** |
The change can only affect USB devices with VID=0x0489 and PID=0xe170.
Users without this specific hardware are completely unaffected. This is
about as low-risk as a kernel patch can be.
### 5. USER IMPACT
- **Affected users**: Those with this specific MediaTek MT7922 Bluetooth
variant
- **Severity without fix**: Bluetooth hardware is completely non-
functional (driver doesn't recognize the device)
- **Impact**: HIGH for affected users - their Bluetooth doesn't work at
all
The commit includes detailed `/sys/kernel/debug/usb/devices` output
showing real hardware, indicating this comes from actual user/vendor
testing.
### 6. STABILITY INDICATORS
- Authored by MediaTek (chip vendor) with direct hardware knowledge
- Reviewed by community member
- Signed off by the Bluetooth subsystem maintainer
- Follows established pattern of many similar MT7922 device ID entries
visible in the diff context
### 7. DEPENDENCY CHECK
- **No dependencies**: This is a self-contained table entry addition
- **Existing support**: The BTUSB_MEDIATEK and BTUSB_WIDEBAND_SPEECH
flags and MT7922 support code exist in all recent stable trees
- **Clean application**: Should apply cleanly to any stable tree that
has MT7922 support
### CONCLUSION
This commit is a textbook example of what SHOULD be backported to
stable:
1. **Falls under Device ID Exception**: Explicitly allowed category for
stable
2. **Fixes Real User Problem**: Enables Bluetooth hardware that would
otherwise be completely non-functional
3. **Minimal Risk**: 2-line table entry addition, cannot break anything
else
4. **No New Features**: Just enables existing driver for new hardware
variant
5. **Well-Reviewed**: Proper sign-offs from vendor and maintainer
6. **Clear Benefit**: Users with this hardware get working Bluetooth
The lack of explicit stable tag is typical for device ID additions -
stable maintainers routinely accept these. The benefit (enabling
hardware) far outweighs the near-zero risk.
**YES**
