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

Hi all,

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

  drivers/usb/roles/intel-xhci-usb-role-switch.c

between commit:

  d2a90ebb6553 ("usb: roles: intel_xhci: Supplying software node for the role mux")

from the pm tree and commit:

  2be1fb64dfeb ("usb: roles: intel: Enable static DRD mode for role switch")

from the usb tree.

I fixed it up (see below) and can carry the fix as necessary. 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.

Cheers,
Stephen Rothwell
