        src/sys/dev/isa: mcd.c
        src/sys/dev/pci: if_iwi.c
        src/sys/dev/raidframe: rf_netbsdkintf.c
        src/sys/dev/scsipi: ses.c

Log Message:
sys/dev: Memset zero before copyout.

Just in case of uninitialized padding which would lead to kernel
stack disclosure.  If the compiler can prove the memset redundant
then it can optimize it away; otherwise better safe than sorry.

I think the iwi(4), mcd(4), and ses(4) changes actually plug leaks;
the raidframe(4) change probably doesn't (but doesn't hurt).
