Is there someone to whom you can turn to for advice?这句话有没有语病

问题描述:

Is there someone to whom you can turn to for advice?这句话有没有语病
两个to有没有重复,或者是什么语法现象

Is there someone to whom you can turn to for advice?
这句话明显多了一个to.turn to sb for sth是一个固定词组.那这句话该怎么改可以改成:Is there someone to whom you can turn for advice?或:Is there someone whom/ who/ that you can turn to for advice?或:Is there someone you can turn to for advice?
