[Intel-gfx] linux-next: manual merge of the drm-misc tree with Linus' tree

Hi all,

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

  sound/pci/hda/hda_intel.c

between commits:

  1ba8f9d30817 ("ALSA: hda: Add a power_save blacklist")
  40088dc4e1ea ("ALSA: hda - Revert power_save option default value")

from Linus' tree and commit:

  07f4f97d7b4b ("vga_switcheroo: Use device link for HDA controller")

from the drm-misc 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.
