Subject: virtio: pci: switch to new PM API
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d077536386595309060dda57e7b7474c501a589b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

virtio: pci: switch to new PM API

The older PM API doesn't have a way to get notifications on hibernate
events.  Switch to the newer one that gives us those notifications.
