Subjectfwnode_for_each_child_node() and OF backend discrepancy
Hi,

I tired to iterate over all child nodes, regardless if they are
available
or not. Now there is that handy fwnode_for_each_child_node() (and the
fwnode_for_each_available_child_node()). The only thing is the OF
backend
already skips disabled nodes [1], making fwnode_for_each_child_node()
and
fwnode_for_each_available_child_node() behave the same with the OF
backend.

Doesn't seem to be noticed by anyone for now. I'm not sure how to fix
that
one. fwnode_for_each_child_node() and also fwnode_get_next_child_node()
are
used by a handful of drivers. I've looked at some, but couldn't decide
whether they really want to iterate over all child nodes or just the
enabled
ones.

Any thoughts?
