Merge tag 'drm-for-v4.15' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "This is the main drm pull request for v4.15. Core: - Atomic object lifetime fixes - Atomic iterator improvements - Sparse/smatch fixes - Legacy kms ioctls to be interruptible - EDID override improvements - fb/gem helper cleanups - Simple outreachy patches - Documentation improvements - Fix dma-buf rcu races - DRM mode object leasing for improving VR use cases. - vgaarb improvements for non-x86 platforms. New driver: - tve200: Faraday Technology TVE200 block. This "TV Encoder" encodes a ITU-T BT.656 stream and can be found in the StorLink SL3516 (later Cortina Systems CS3516) as well as the Grain Media GM8180.
