From b946d286114e09a81c303c7ec8ec3f7b33dff9e8 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Wed, 23 Sep 2015 13:04:47 -0600 Subject: [PATCH] vfio/pci: Cleanup ATI 0x3c3 quirk This is an easy quirk that really doesn't need a data structure if its own. We can pass vdev as the opaque data and access to the MemoryRegion isn't required.
