Yes, I have seen that. I do not think it will be accepted (it is just too 
unclear), but you will see.

Create a separate patch that can be applied independently. As a mentor, I 
suggest to first send the patch only to me and the linux-kernel-mentees 
list, so that you get some first feedback without bothering the 
maintainers and them losing patience to work with you.

I suggest to work on this patch here first and then revisit the other 
patch for revert commits you created.

I suggest to implement a check if a commit message contains quotes. Then, 
we can check on previous commits how often that would trigger and see if 
we find legitimate cases where quotes really make sense; then we can 
improve checkpatch.pl to handle those well when refering to such commits.
