[PATCH v2] [media] uvcvideo: Add iFunction or iInterface to device names.

2017-04-17 Thread Peter Boström
Permits distinguishing between two /dev/videoX entries from the same physical UVC device (that naturally share the same iProduct name). This change matches current Windows behavior by prioritizing iFunction over iInterface, but unlike Windows it displays both iProduct and iFunction/iInterface
