From: Alexander Lobakin <alobakin@xxxxx> commit 897c44f0bae574c5fb318c759b060bebf9dd6013 upstream. rproc_serial_id_table lacks an exposure to module devicetable, so when remoteproc firmware requests VIRTIO_ID_RPROC_SERIAL, no uevent is generated and no module autoloading occurs. Add missing MODULE_DEVICE_TABLE() annotation and move the existing one for VIRTIO_ID_CONSOLE right to the table itself.
