Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: vmwgfx: Use kcalloc instead of kzalloc to allocate array drm/i915: fix infinite recursion on unbind due to ilk vt-d w/a drm/radeon/kms: fix return type for radeon_encoder_get_dp_bridge_encoder_id
