From 9a383051b57ea6ef073d6e248d445b031ff38b6a Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Wed, 14 Feb 2018 23:20:00 -0600 Subject: [PATCH 3580/4131] drm/amdgpu_gem: fix error handling path in amdgpu_gem_va_update_vm MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, if amdgpu_vm_bo_update() fails, the returned error is being ignored. Fix this by properly checking _r_ after calling amdgpu_vm_bo_update. Also, remove redundant code just before label _error_.
