From 6bde6aaac6f2af14557ef65f5eb053cb135ca173 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Mon, 25 Oct 2010 07:46:47 +0200 Subject: pcie: clean up hot plug notification Simplify logic for hotplug notification, by tracking state of the logical interrupt condition. We then simply use this variable to make the interrupt decision, according to spec. API is made cleaner as we no longer force users to pass in old slot control value.
