The topology loader in soc-topology.c is currently accepting ABI version mismatches for some topology components in order to keep backwards compatibility with ABIv4. When dealing with these ABI mismatch situations, temporary copies of the v4 objects are allocated and passed on to the right driver topology handlers. After that they're supposed to be freed. However, memory leaks are currently possible in soc_tplg_link_elems_load() and also soc_tplg_manifest_load(). These patches fix these. I've originally created a PR on github for SOF at: https://github.com/thesofproject/linux/pull/1771 as my impression was this can affect older SOF toplogies. But as it turns out this may impact Skylake instead.
