Won’t that cause conflicts now with the patch *[RESEND PATCH v1] Bluetooth: btusb: MT7922: Add VID/PID 0e8d/223c*, and shouldn’t it be send as a series.

Hi Luiz,
I wanted to kindly follow up on two patches about adding MediaTek's Bluetooth ID to usb table in btusb driver.
"Bluetooth: btusb: MT7925: Add VID/PID 0e8d/8c38"
"Bluetooth: btusb: MT7922: Add VID/PID 0e8d/223c"
Is there any missing information I didn't provide or concerns that are preventing these two changes from being processed?
Thanks a lot!
