- * __video_register_device - register video4linux devices
- * @vdev: video device structure we want to register
- * @type: type of device to register
- * @nr: which device node number (0 == /dev/video0, 1 == /dev/video1, ...
- * -1 == first free)
- * @warn_if_nr_in_use: warn if the desired device node number
- * was already in use and another number was chosen instead.
- * @owner: module that owns the video device node
- *
- * The registration code assigns minor numbers and device node numbers
- * based on the requested type and registers the new device node with
- * the kernel.
- *
- * This function assumes that struct video_device was zeroed when it
- * was allocated and does not contain any stale date.
- *
- * An error is returned if no free minor or device node number could be
- * found, or if the registration of the device node failed.
- *
- * Zero is returned on success.
- *
- * Valid types are
- *
- * %VFL_TYPE_GRABBER - A frame grabber
- *
- * %VFL_TYPE_VBI - Vertical blank data (undecoded)
- *
- * %VFL_TYPE_RADIO - A radio card
- *
- * %VFL_TYPE_SUBDEV - A subdevice
- *
- * %VFL_TYPE_SDR - Software Defined Radio
