[patch -NEXT] usb/gadget/webcam: fix Kconfig depends again

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>

The USB gadget webcam driver uses V4L2 interfaces, so it should depend
on VIDEO_V4L2 instead of VIDEO_DEV.  This fixes a lot of build errors
when V4L2 is not enabled:

ERROR: "v4l2_event_unsubscribe" [drivers/usb/gadget/g_webcam.ko] undefined!
