Hi Rob, Saravana, Tomi, Laurent, Sakari, Mark

This is v6 patch-set

Current Of-graph has "endpoint base" for loop, but doesn't have
"port base" loop. "endpoint base" loop only is not enough.
This patch-set add new "port base" for loop, and use it.

Unfortunately, new helper function need to call of_node_get()
if dts doesn't have "ports" node, so we can't replace existing
loop by new helper, because it is using "const".

I noticed that some developer posted the patch to ALSA ML and
its and [5/9][6/9] patch will conflict. I think it is better to
repost these to ALSA ML *after* main patches (= [1/9][2/9]) were
included to linus/master tree (?). (Mark, can you agree ?)
So, [5/9][6/9] wants "review" only here.

v5 -> v6
	- based on latest linus/master branch
	- [9/9]: fixed compile warrning

v4 -> v5
	- tidyup comments
	- [8/9]: parent NULL check was removed
	- [9/9]: use for_each_of_graph_port()

v3 -> v4
	- new for_each loop includes __free()
	 - comment indicates to use return_ptr() or no_free_ptr() if
	   it need to continue to use node
	 - each driver based on it
	- care "prev" leak on of_graph_get_next_ports()
	- of_graph_get_next_port_endpoint() indicates WARN() if port
	  has non-endpoint node
	- tidyup each git-log

v2 -> v3
	- return NULL if it it doesn't have ports / port
	- add visible comment on of_graph_get_next_ports()

v1 -> v2
	- add each Reviewed-by / Acked-by
	- tidyup/update Kernel Docs
	- use prev as parameter
	- update git-log explanation
	- remove extra changes
