Whichever approach is chosen it should be consistent across drivers and this patch needs more discussion. Furthermore, I'm convinced that we have to stop playing games trying to decipher the "meaning" of NEC scancodes (what's the customer/vendor/address, which byte is the MSB, etc). I'll post separate proposals to that effect later.
