In order to receive events generated by subdevices on the video capture nodes, those events need to be forwarded to the subdevice's list of reachable video capture devices. Note this will queue the event to a video device even if there is no actual _enabled_ media path from the sub-device to the video device. So a future improvement is to skip the video device if there is no enabled path to it from the sub-device. The entity->pipe pointer can't be used for this check because in imx-media a sub-device can be a member to more than one streaming pipeline at a time.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
