Could I send a patch which I'm not sure it was correct?

Hi I found a bug and send a trivial patch to fix it. The kind maintainer gave me some advice about this patch. I'm not familier with it and this is a challenge to me, I want to do it as my best, but I'm afraid that it is impolite to send a patch, which I'm not sure it was correct! This is my first time to send a patch to the kernel, any advice is appreciated! Regards, Wei Zhang
