[PATCH 2/2] drm/tegra: Use dma_buf from GEM object instance

Thomas Zimmermann
2025-06-19T11:34:48Z

Avoid dereferencing struct drm_gem_object.import_attach for the
imported dma-buf. The dma_buf field in the GEM object instance refers
to the same buffer. Prepares to make import_attach an implementation
detail of PRIME.
