I see a gvt-next-2022-04-29 tag adding the following fixes:

419f8299ddad i915/gvt: Fix NULL pointer dereference in init_mmio_block_handlers
5b95b9d58fb0 drm/i915/gvt: Fix the compiling error when CONFIG_DRM_I915_DEBUG_RUNTIME_PM=n
fa630c304b93 drm/i915/gvt: Make intel_gvt_match_device() static

I'm expecting that's my new merge target once a pull request is
completed for that.  Please keep me cc'd.  Thanks,

Alex
