- Construct string with (dev is struct em28xx *dev)

dev_name(&dev->udev->dev)

dev->tuner_addr
What guarantees this won't get confused by hot plugging and re-use of the
bus slot ?
Good point. Yes, this should be addressed.
This resource should be destroyed when em28xx_ handles unplug from its
em28xx_usb_disconnect() or in generic words, in its "uninit". It is a
matter of making sure this resource is handled in the "uninit" for this
media device/driver(s) like any other shared resource.
Would that cover the hot plugging and re-use of the bus slot scenario?
