From: Thomas Zimmermann Date: Thu, 19 Jun 2025 11:27:01 +0000 (+0200) Subject: drm/tegra: Use dma_buf from GEM object instance X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=482c7e296edc0f594e8869a789a40be53c49bd6a;p=thirdparty%2Fkernel%2Flinux.git drm/tegra: Use dma_buf from GEM object instance 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.
