At beginning of probe() function, the driver iterates over OF children and assigns found device node for later. The code uses for_each_available_child_of_node() which drops the references on children on each successful pass, thus the probe function operates later on the device node without holding the reference. Fix this by increasing the reference count for found child node and drop it at the end of the probe, because it is not needed further (the V4L init code takes its own references).

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 reStructuredText 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.
