The subtraction of the two pointers is automatically scaled by the
size of the size of the object the pointers point to, so the division
by sizeof(*i2400m->barker) is incorrect.  This has been broken since
day one of the driver and is only debug, so remove the debug completely.

Also move && in condition to clean up a checkpatch warning.
