just in case are you aware of this discussion regarding goto labels
http://lkml.iu.edu/hypermail/linux/kernel/0706.0/0809.html ?

Practically there is no big need (neither it is a clean-up IMHO)
to change column 1 indentation of goto labels, however I do agree that
^[a-z0-9_]\+:$ style of goto labels is 10 times more commonly used,
and that means it's a good time to update my ~/.emacs config.

Someone may want to fix the style of another 5000+ goto labels one day,
though it is better to have an officially agreed policy beforehand.

Anyway I do not strictly object against the change, see one my comment
below and feel free to add my

Since you are here, can you sort headers out, please?

And I'm pretty sure some more inclusions can be safely removed
from the list.

Actually I was not aware of that discussion, thanks for pointing this
out. Mostly I encountered the style without indentation but of course
that does not mean it is the only one.

You mean sort by name (or by christmas tree)? I can... I am not sure
about benefits of such patch (which should be the motivation for change).

I checked them while removing delay - all of them seem to be used.

Best regards,
Krzysztof

Thank you in advance.

In general it simplifies navigation through the list of headers for
humans IMHO.

By example, let's look at drivers/media/usb/dvb-usb/dw2102.c :

#include "dw2102.h"
#include "si21xx.h"
#include "stv0299.h"
#include "z0194a.h"
#include "stv0288.h"
#include "stb6000.h"
#include "eds1547.h"
#include "cx24116.h"
#include "tda1002x.h"
#include "mt312.h"
#include "zl10039.h"
#include "ts2020.h"
#include "ds3000.h"
#include "stv0900.h"
#include "stv6110.h"
#include "stb6100.h"
#include "stb6100_proc.h"
#include "m88rs2000.h"
#include "tda18271.h"
#include "cxd2820r.h"
#include "m88ds3103.h"
#include "ts2020.h"

Was it obvious for an author/reviewers that commit 0fecb6c0944f adds a
duplicate?

What is the chance to add a duplicate, if the list of headers is sorted?

Good, thank you for checking it :)
