  • The media_devnode structure provides support for registering and
    unregistering character devices using a dynamic major number. Reference
    counting is handled internally, making device drivers easier to write
    without having to solve the open/disconnect race condition issue over
    and over again.

    The code is based on video/v4l2-dev.c.
