Hi all,
After merging the drm-intel-fixes tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/gpu/drm/i915/gvt/kvmgt.c: In function 'intel_vgpu_open':
drivers/gpu/drm/i915/gvt/kvmgt.c:511:32: error: dereferencing pointer to incomplete type 'struct mdev_device'
vfio_unregister_notifier(&mdev->dev, VFIO_GROUP_NOTIFY,
^
Caused by commit
99e3123e3d72 ("vfio-mdev: Make mdev_device private and abstract interfaces")
from the vfio-fixes tree interacting with commit
364fb6b789ff ("drm/i915/gvt/kvmgt: prevent double-release of vgpu")
from the drm-intel-fixes tree.
I applied this merge fix patch:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Tue, 3 Jan 2017 10:38:48 +1100
Subject: [PATCH] vfio-mdev: fixup for "Make mdev_device private and abstract interfaces"
