[Intel-gfx] [PATCH 05/15] drm/i915: Only refcount ppgtt if it actually is one

This essentially unbreaks non-ppgtt operation where we'd scribble over random memory. While at it give the vm_to_ppgtt function a proper prefix and make it a bit more paranoid. Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_drv.h | 10 +- drivers/gpu/drm/i915/i915_gem.c
