SCK is called from mieqProcessInputEvents each time a keyboard event is

If you have pDev->key being NULL suggests either a non-keyboard device sends
key events (in which case it should crash during GetKeyboardValuatorEvents
anyway*) or memory is somewhat screwed.


* not sure if you use GKVE, GetPointerEvents, ... in the apple branch.
