I would argue that the user has set his speed setting on purpose, so chances
of this happening are not that great. On the other hand, they might simply
forget that they changed it to a fixed value and be in different
conditions, now.
So yes, it is a good idea to only raise the value.

Well, a single printk could solve this problem.

My reason is that I don't like my machine becoming too warm. I prefer a
little noise over a higher temperature. Thus, I keep my laptop at level 4.
In warmer conditions or when CPU usage is high, I keep it at 7.
I would like to ask you to at least keep level 7 if level 7 was set before.
Personally, I would not mind restoring from 4 to 7, but that would probably
be confusing to everyone who does not know of this intended behaviour.
Ideally, it would simply restore from 4 to 4, though.
I agree that off is not a good level to restore to, btw.
