Merge branch 'of_get_available_child_by_name'
Biju Das says:
====================
Add of_get_available_child_by_name()
There are lot of net drivers using of_get_child_by_name() followed by
of_device_is_available() to find the available child node by name for a
given parent. Provide a helper for these users to simplify the code.
v1->v2:
* Make it as a series as per [1] to cover the dependency.
* Added Rb tag from Rob for patch#1 and this patch can be merged through
net as it is the main user.
* Updated all the patches with patch suffix net-next
* Dropped _free() usage.
