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

Hi Takashi,

Today's linux-next merge of the sound tree got a conflict in
sound/pci/hda/hda_intel.c between commit 246efa4a072f ("snd/hda: add
runtime suspend/resume on optimus support (v4)") from the drm tree and
commit 7d4f606c50ff ("ALSA: hda - WAKEEN feature enabling for runtime
pm") from the sound tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
