Then I use "git diff" to generate the patch. Why not commit? A simple way to do this would be. 1. Make changes as per requirements 2. Commit them 3. Use `git format-patch` to generate patches. 4.

I see no reason to review someone's lex code. I guess very few people are actually willing to do that. Why don't you just send in the diff? Or even better, the patch you intend to submit.

Solving checkpatch error with lex
Hello,
was trying to fix the checkpatch error of not using c99 comments in the
file
drivers/staging/rtl8192u/r8192U_dm.c
so I wrote a lex program to do so since there were way too many to do it
manually.
Could anyone have a look at my lex code and tell me if I need to change it.
I have attached the lex code.
As per my testing it works perfectly, would love a second opinion.
Thanks,
Karthik

Nope, you are doing two different _types_ of checkpatch fixes. So it
needs to be more than one patch.
Remember, you need to make it as easy as possible for a maintainer to
read your patch, doing more than one thing in a patch makes it much
harder, and it gives them an easy reason to reject to it.

Don't do multiple things in the same patch, make this at least 2
patches.

Wouldn't this count as one checkpatch fix patch? I mean, being the same
