From a2b201f83971df03c8e81a480b2f2846ae8ce1a3 Mon Sep 17 00:00:00 2001 From: Pierre-Eric Pelloux-Prayer Date: Tue, 25 Jun 2024 14:31:34 +0200 Subject: [PATCH] drm/radeon: check bo_va->bo is non-NULL before using it [ Upstream commit 6fb15dcbcf4f212930350eaee174bb60ed40a536 ] The call to radeon_vm_clear_freed might clear bo_va->bo, so we have to check it before dereferencing it.
