As a follow-up in the style of:873be895ed("udev: add USB revision in ID_PATH") this patch adds a second symlink for media controllers, this time including the USB revision. This means that in addition to persistent symlinks like: pci-0000:04:00.3-usb-0:1:1.0-media-controller -> ../../media0 We now also get: pci-0000:04:00.3-usbv2-0:1:1.0-media-controller -> ../../media0 ...which helps distinguish media devices plugged into different USB root hubs provided by the same PCI card, at least as long as they are for different USB revisions. Fixes:04f19d6735("udev: Add /dev/media/by-path symlinks for media controllers")
