Hi Arend

Yes, a script that had been excellent, I think!
I have one as part of my git send-email script, until a week ago, it
was enough that I removed the "drivers/" and changed all "/" to ": "
I have now been expanded my sed pipe a lot (tell me if anyone is interested)
But now I've seen everything from uppercase and [DIR], etc.
So I can not understand how anyone should be able to get the right
name without a good help.

Sure i like to share how I use cppcheck, but is very hesitant to write
this with each patch mails I send though!

I run:
cppcheck --force --quiet --enable=all .

Or a specific file instead of .

This will include, among other things get a lot of error message such,
+4000 for the kernel.
(style) The function 'xxx' is never used

For these I made a script that searched through all the files after
the function name (cppcheck missed a few). And save the rest so I go
through them and possibly send patches.


Kind regards
Rickard Strandqvist
