The UVC_DEV_DISCONNECTED flag is set when the USB device is disconnected, and checked in the open() handler to refuse opening a device that has been disconnected. This is inherently racy, but the race condition is taken care of in the V4L2 core, which also fails open() calls when the V4L2 device node has been unregistered. As the uvcvideo USB disconnect handler unregisters all its video device nodes, the UVC_DEV_DISCONNECTED flag doesn't serve any purpose anymore and can be removed.
