Merge tag 'drm-fixes-for-v4.10-rc6' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"drm fixes across the board.
Okay holidays and LCA kinda caught up with me, I thought I'd get some
of this dequeued last week, but Hobart was sunny and warm and not all
gloomy and rainy as usual.
This is a bit large, but not too much considering it's two weeks stuff
from AMD and Intel.
core:
- one locking fix that helps with dynamic suspend/resume races
i915:
- mostly GVT updates, GVT was a recent introduction so fixes for it
shouldn't cause any notable side effects.
amdgpu:
- a bunch of fixes for GPUs with a different memory controller design
that need different firmware.
exynos:
- decon regression fixes
msm:
- two regression fixes
etnaviv:
- a workaround for an mmu bug that needs a lot more work.
virtio:
- sparse fix, and a maintainers update"
