[PATCH 1/4] of/unittest: remove use of node name pointer in overlay high level test

From: Rob Herring
Date: Tue Aug 28 2018 - 11:53:22 EST


In preparation for removing the node name pointer, it needs to be
removed from of_unittest_overlay_high_level. However, it's not really
correct to use the node name without the unit-address and we should use
the full node name. This most easily done by iterating over the child
nodes with for_each_child_of_node() which is what of_get_child_by_name()
does internally. While at it, we might as well convert the outer loop to
use for_each_child_of_node() too instead of open coding it.
