linux-next: manual merge of the staging tree with the v4l-dvb tree

Hi all,

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

  drivers/staging/media/imx/imx-media-dev.c

between commit:

  b803cd359833 ("media: staging/imx: Switch to v4l2_async_notifier_add_*_subdev")

from the v4l-dvb tree and commit:

  f93861c2d611 ("staging: Convert to using %pOFn instead of device_node.name")

from the staging 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.
