Hi amilsananak,

add the necessary information in the commit message.

Look at this example, which is also adding support for a webcam

commit 53c264544dfce30f7741a2b1e78f90d046e5d8ff
    media: uvcvideo: Add support for Apple T2-attached FaceTime HD Camera

    Adds the requisite device id to support detection of the Apple FaceTime
    HD webcam exposed over the T2 BCE VHCI interface.

look at the git log to see more examples
$ git log drivers/media/usb/uvc/uvc_driver.c

I think you should add a comment containing the name of the camera model you
want to add support for. Look at other examples in uvc_ids[]

e.g. look at this comment for a camera also from Quanta

	/* Quanta USB2.0 HD UVC Webcam */
