In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memset(), avoid intentionally writing across
neighboring fields.

Add struct_group() to mark region of struct kone_mouse_event that should
be initialized to zero.

Applied, thank you Kees.

Eek! No, this will break the build: struct_group() is not yet in the tree.
I can carry this with an Ack, etc.

I was pretty sure I saw struct_group() already in linux-next, but that was 
apparently a vacation-induced brainfart, sorry. Dropping.

Cool, no worries. Sorry for the confusion!
