the double alloc looked a little funny, but i didnt dive deep into the
details.  but as you point this out, it seems to make sense to me.
any problems with that change Javier ?

i.e. we do:
struct ... { ... unsigned short keycode[NUM_KEYS]; }
rather than doing two calls to kmalloc

considering this is a piece of "hardware" implemented in FPGAs, i
think it's ok too.  if someone really needs more flexibility, then
they're free to extend the driver and submit a patch :).
