linux-next: manual merge of the drm tree with the pci tree

Hi all,

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

  drivers/gpu/vga/vga_switcheroo.c

between commit:

  99efde6c9bb7 ("PCI/PM: Rename pci_wakeup_bus() to pci_resume_bus()")

from the pci tree and commit:

  9572e6693cd7 ("vga_switcheroo: simplify the return expression of vga_switcheroo_runtime_resume")

from the drm 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.

Thanks for the fix Stephen! Looks correct to me.

This is now a conflict between the pci tree and Linus' tree.
