If it's just been put on the cake and you are still smoothing the cake, you should be able to remove a good bit of the cracking by rubbing gently with your fingertips then going over with a smoother.
If the fondant has been allowed to harden there's not a lot that you can do that's not noticeable other than fill in with a bit of soft royal icing in the same colour as the fondant and smooth it over with damp fingertips.
