This max_adj is only important when the local clock offset is large and user space chooses not to step the time value. In that case, user space will want to run the clock as fast (or as slow) as possible in order to catch up with the remote clock.
The driver must provide a max_adj that is always safe for user space to apply via the clock_adjtime() system call.
