parentdrm/tegra: Unconditionally select IOMMU_IOVA (diff)
drm/tegra: hub: Remove bogus connection mutex check
The Tegra DRM never actually took that lock, so the driver was broken until generic locking was added in commit: commit b962a12050a387e4bbf3a48745afe1d29d396b0d Author: Rob Clark <robdclark@gmail.com> Date: Mon Oct 22 14:31:22 2018 +0200 drm/atomic: integrate modeset lock with private objects It's now no longer necessary to take that lock, so drop the check. v2: add rationale for why it is now safe to drop the check (Daniel) Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Thierry Reding <treding@nvidia.com>
