Subject: linux-next: manual merge of the sound-asoc tree with the pm tree

Hi all,

Today's linux-next merge of the sound-asoc tree got a conflict in:

  drivers/of/base.c

between commit:

  1df09bc66f9b ("of: Move OF property and graph API from base.c to property.c")

from the pm tree and commits:

  4c9c3d595f1b ("of_graph: add of_graph_get_remote_endpoint()")
  0ef472a973eb ("of_graph: add of_graph_get_port_parent()")
  ac1e6958d3be ("of_graph: add of_graph_get_endpoint_count()")

from the sound-asoc tree.

This pm tree commit appeared briefly in the devicetree tree 9 days ago,
so I have done the same resolution as I did then.

I added the merge fix patch below. This is now fixed as far as linux-next
is concerned, but any non trivial conflicts should be mentioned to your
upstream maintainer when your tree is submitted for merging.  You may
also want to consider cooperating with the maintainer of the conflicting
tree to minimise any particularly complex conflicts.
