This fails to build with:
sys/modules/ctl/../../cam/ctl/ctl.c:12522:27: error: member reference
base type 'void' is not a structure or union
mtx_assert(&CTL_SOFTC(io)->ctl_lock, MA_NOTOWNED);
Looks like thep roblem is that CTL_SOFTC indeed does not cast and
returns void instead:
+#define CTL_SOFTC(io) ((io)->io_hdr.ctl_private[CTL_PRIV_LUN].ptrs[1])
