A number of fixes:
  - bridge:
    - samsung-dsim: fix GPIO lifetime
  - client: Null pointer dereference fix
  - imagination: error handling fix, page handling fix
  - nouveau: fix reference leaks, double-frees, out-of-bounds accesses,
    use-after-frees, don't reject config without SCDC,  a number of
    workarounds
  - virtio: fix memory leak, reference leaks, null pointer dereference,
