[PATCH][next] drm/amd/amdgpu: Fix missing error return on kzalloc failure
Posted by Colin Ian King 1 month ago
Currently the kzalloc failure check just sets reports the failure
and sets the variable ret to -ENOMEM, which is not checked later
for this specific error. Fix this by just returning -ENOMEM rather
than setting ret.
