From 515986100d176663d0a03219a3056e4252f729e6 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Wed, 25 Jun 2025 10:42:18 +0200 Subject: drm/amdgpu: Use dma_buf from GEM object instance MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
