Maximilian Heyne fbc9a8718f virtio-mmio: fix memory leak of vm_dev ... commit fab7f25922 upstream. With the recent removal of vm_dev from devres its memory is only freed via the callback virtio_mmio_release_dev. However, this only takes effect after device_add is called by register_virtio_device. Until then it's an unmanaged resource and must be explicitly freed on error exit. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.
