Subject: drm/amdgpu: plumb error handling though amdgpu_benchmark()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: e460f244fbe847904abd767e4ae093bad699f218
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
So we can tell when this function fails.
v2: squash in error handling fix (Alex)
