| |
The current code creates a sysfs device path where the video4linux device is child of the usb device itself instead of the interface it belongs to. That is evil and confuses udev.
This patch does basically the same thing as Kay's similar patch for the ov511 driver:

(A while back I sent this patch to Mauro, but it never appeared in any tree, so I am reposting this on lkml, in the hope someone will pick it up.)
