This adds USB ID `0x0bda/0xd922` for Realtek RTL8922AE to `quirks_table[]` in btusb — a 2-line device-ID addition, same pattern as the existing `0x8922` entry. RTL8922A support is already in this tree; the patch applies cleanly; maintainer-reviewed. The follow-up repo searches didn’t change that: broad `--grep="d922"` hits were mostly false positives (hash substrings), and the exact commit (`480dcc68f2826`) lives on `autosel`, not on the current stable checkout. drivers/bluetooth/btusb.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/bluetooth/btusb.c b/drivers/bluetooth/btusb.c index 2f7ff83ee78ca..6d4c5d75cfc61 100644 --- a/drivers/bluetooth/btusb.c +++ b/drivers/bluetooth/btusb.c @@ -602,6 +602,8 @@ static const struct usb_device_id quirks_table[] = { /* Realtek 8922AE Bluetooth devices */ { USB_DEVICE(0x0bda, 0x8922), .driver_info = BTUSB_REALTEK | BTUSB_WIDEBAND_SPEECH }, + { USB_DEVICE(0x0bda, 0xd922), .driver_info = BTUSB_REALTEK | + BTUSB_WIDEBAND_SPEECH }, { USB_DEVICE(0x13d3, 0x3617), .driver_info = BTUSB_REALTEK | BTUSB_WIDEBAND_SPEECH }, { USB_DEVICE(0x13d3, 0x3616), .driver_info = BTUSB_REALTEK | -- 2.53.0
