Subject: linux-next: manual merge of the pci tree with Linus' tree

Hi Bjorn,

Today's linux-next merge of the pci tree got a conflict in
drivers/pci/quirks.c between commit c2fb8a3fa255 ("USB: add
NO_D3_DURING_SLEEP flag and revert 151b61284776be2") from Linus' tree and
commit fbebb9fd2258 ("PCI: add infrastructure for devices with broken
INTx masking") from the pci tree.

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

Cheers,
