* EVIOCGMTSLOTS(len) - get MT slot values
*
* The ioctl buffer argument should be binary equivalent to
*
* struct input_mt_request_layout {
* __u32 code;
* __s32 values[num_slots];
* };
*
* where num_slots is the (arbitrary) number of MT slots to extract.
*
* The ioctl size argument (len) is the size of the buffer, which
* should satisfy len = (num_slots + 1) * sizeof(__s32). If len is
* too small to fit all available slots, the first num_slots are
* returned.
*
* Before the call, code is set to the wanted ABS_MT event type. On
* return, values[] is filled with the slot values for the specified
* ABS_MT code.
*
* If the request code is not an ABS_MT value, -EINVAL is returned.
