commit2692c614f8upstream. When device_get_child_node_count() got split to the fwnode and device respective APIs, the fwnode didn't inherit the ability to traverse over the secondary fwnode. Hence any user, that switches from device to fwnode API misses this feature. In particular, this was revealed by the commit1490cbb9db("device property: Split fwnode_get_child_node_count()") that effectively broke the GPIO enumeration on Intel Galileo boards. Fix this by moving the secondary lookup from device to fwnode API. Note, in general no device_*() API should go into the depth of the fwnode implementation.

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.
