This breaks rfkill.. There are automated test scripts for testing this
area (and most of Wi-Fi for that matter. It would be nice if these were
used for changes before they get contributed upstream..
http://buildbot.w1.fi/hwsim/
This specific commit broke all the rfkill_* test cases because of
following:

Note that RFKILL_TYPE_ALL here..

It was included for RFKILL_OP_CHANGE_ALL.

but not for RFKILL_OP_CHANGE..
This needs following to work:
diff --git a/net/rfkill/core.c b/net/rfkill/core.c
index 59ff92d..c4bbd19 100644

rfkill_set_block(rfkill, ev.soft);
ret = 0;
break;
