When called from
if (atkbd_reset)
if (atkbd_command(atkbd, NULL, ATKBD_CMD_RESET_BAT))
in atkbd_probe, we'll crash trying to write back the results
into the null pointer.
The interface to atkbd_command seems more sensible to allow
a null pointer to indicate that the caller doesn't care about
the received data than to supply a dummy pointer here.
