video_device is initialized you *do* know which parent PCI device to use and
so you set dev_device to the correct PCI device.
- flags: optional. Set to V4L2_FL_USE_FH_PRIO if you want to let the framework
handle the VIDIOC_G/S_PRIORITY ioctls. This requires that you use struct
v4l2_fh. Eventually this flag will disappear once all drivers use the core
priority handling. But for now it has to be set explicitly.
