Because when you look at the callsite:

ctx->make_space_for_cs_id(ctx);

and compare it with the version I'm suggesting:

ctx->ret_addr = ctx->add_coherent_slave_id_slice(ctx);

my version says exactly what it does: it adds the bit slice of CS ID to
ret_addr. You don't even have to look at the function body in order to
know what's going on.
