Some of the alignment doesn't seem to match local style which
is either align after ( or align 4 spaces in from line above for
multiple line argument lists.
Code is fine as I guess the later structure is to prepare
for additions that prevent early returns being sensible.
With that in mind.

Alignment looks fishy plus maybe move &read_ack_register up a line.

I guess later changes make it unwise to just return -1 here.

or return here.
