From: David Stevens Date: Wed, 11 Aug 2021 04:04:01 +0000 (+0900) Subject: drm/virtio: set non-cross device blob uuid_state X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=3c383a3688b7d8bc83ed22b36d0fb50db0bd2608;p=kernel.git drm/virtio: set non-cross device blob uuid_state Blob resources without the cross device flag don't have a uuid to share with other virtio devices. When exporting such blobs, set uuid_state to STATE_ERR so that virtgpu_virtio_get_uuid doesn't hang.
