[U-Boot] [PATCH] cmd_nvedit.c: clean up with checkpatch

[Macpaul Lin]

Code clean up of cmd_nvedit.c by using checkpatch.pl.

Signed-off-by: Macpaul Lin <macpaul@andestech.com>
---
Note:
  This patch has fixed most of the ERRORs and WARNINGs in cmd_nvedit.c.
  However, the remains were not clean up for avoiding broken the consistence.

Do you mean the replacement with space to ident?

According to the 2.6.38.1's checkpatch, it reported:
WARNING: please, no spaces at the start of a line
#90: FILE: common/cmd_bdinfo.c:61:
+    defined(CONFIG_8260) || defined(CONFIG_E500)$

We have got lots of such warnings.

I think we can use little pieces of times to do the cleanup work.
If Wolfgang has no comment to such coding style clean up,
I'll do it slowly when I have time.

Thanks.

this particular check has already been posted upstream as generally causing 
more harm than good.  but getting checkpatch fixed often feels glacial.

up to Wolfgang how he feels about ifdef indentation

Thanks for your information, I didn't read that article before.
Could you provide the URL of related discussion that could be found in
the mailing list?

> up to Wolfgang how he feels about ifdef indentation
> -mike

Sure. I think we can discuss about it and then decides how to deal with it. :)
Just waiting for Wolfgang's opinion and see if the revised patch is
need to be send.

In this specific case of #ifdef indentation I feel that the original
form (which causes checkpatch warnings) is actually easier to read, so
I tend to keep it.  But I am aware that this is inconsequent as we ask
for "indentation by TAB only" everywhere else.

So I'm really torn - if it was for myself only I would not hesitate to
leave this part as is, but I realize that quite a number of users have
already complained about the unclear rules and exceptions we make with
the coding style requirements, and some actually threw in the sponge
because of that.

I'm afraid I'm not much of help here.

Best regards,

Wolfgang Denk

well, this is a case where i would say a soft rule is OK -- i.e. allow both 
options and let the active maintainer of the code in question decide.  i too 
prefer the current style as i find it easier to read, but if someone

[U-Boot] [PATCH] cmd_nvedit.c: clean up with checkpatch

For this specific #ifdef case, I will agree to keep the origin format,
it's exactly easier to read.
Because I'm not in the office, I can only send the fixed patch v2 until 4/18.

Yes, use common sense is really too lose for many people.

Checkpatch is really help for people to maintain the consistence for
coding style and also avoid the coding method which might lead logic
failure.
However, the drawback is that we still have effort to think about if
the warning should be correct up according to every case that has been
 reported by checkpatch.

For example, 80 charecters is the most often case. Sometimes the code
is really easier to be read in the single one line. Sometimes the
complicated code that should be execute in one line is really hard to
be modified into short format to avoid exceeding the 80 charecters
lenght rule. Although most of time people can decide which format is
better for human reading than checkpatch's parsing result.
We still have effort to inform the patch commiters to modified the
code and discuss with it.

Also, the coding style clean up for the old code already exist in git
repository will help the new contributers and reduce the disscusion
effort passively.
That's why I think we can do clean up for old code slowly when someone
have time.

Maybe list a exception form and some soft rules on the web page is
sometimes help to the contributers just new to the u-boot project.

I have an idea to recruit some colledgue students locally as
volunteers to clean up the old code according to "checkpatch". They
just do code clean up. By doing this activity will also make them be
familiar with the open source projects. At the same time they can also
be familiar with git CVS. Of course a guideline for such code clean up
activity must be work out first.

Don't know what do you think of it?

Thanks.

Been there too, once. :(

If the goal is to have the !defined aligned, then maybe a solution here 
would be toput a tab rather than a space after the #if?

Ack to the whole of this. Until there is such a list, the casual patch 
committers will either not apply checkpatch, or apply a zero-warning 
strategy.

Maybe your students could successfully get some U-boot-friendly patches 
applied to checkpatch? I tried some time ago for an option to control 
the line length, but gave up because there seemed to be no reaction -- 
see <https://patchwork.kernel.org/patch/149941/>. Having someone who's 
job description actually includes "nagging the checkpatch maintainer 
until the frigging patches are accepted" could help.

Maybe a better option than adding ad hoc options would be a single patch 
to make checkpatch.pl load a custom set of checking rules that could 
supersede the original ones. The set could be contained in the current 
directory as ./.checkpatch.rules (and maybe also look in $(HOME) if not 
found in $(PWD). Not too sure this is technically feasible, though.

I agree - Aligned looks cleaner and easier to read (especially if the logic
is multi-levelled) and shutting up checkpatch by using a tab rather than a
space is an easy solution

But, fwiw, once the patch is applied and everything is nicely aligned and
reads well, who's going to care that checkpatch complained?

Graeme

Do you guys means
#if"\t"defined (XXXXXX) ||
"\t"defined (XXXXXX)
instead of
#if defined (XXXXXX) ||
"space*4" defined (XXXXXX)
?

If so, I'll fix the patch and then send v2 on next Monday and see if
everybody feel this will be better.

Still, the patch fails for me:

Sorry when I replied your mail was doing other things busy so I didn't
catch up your reply.
I didn't hand edit my patch.
Are you applying the Patch v3?
Could you provide the git hash (commit number) to me.
The 3 commits before this patch v3 is

a01ebd: mpc52xx, digsy_mtc
71d19f30: rtc, rv3029

Thanks.

Visual inspection shows only cosmetic changes, so the patch looks good.

For the next time, we should follow the (newly added) clause in our
wiki[1] and have a ommit text like "cosmetic: code cleanup of
cmd_nvedit.c using checkpatch.pl".

As this is very new, I won't insists, so

Acked-by: Detlev Zundel <dzu@denx.de>

Thanks!
  Detlev

Q: Does that mean we also shouldn't be using IRQF_SAMPLE_RANDOM on
   interrupt [sources]?
A: Yes. The flag needs to be taken out and shot.

It took him several minutes to understand any new idea  put  to  him,
and  this is a very valuable trait in a leader, because anything any-
one is still trying to explain to you after two minutes  is  probably
important  and anything they give up after a mere minute or so is al-
most certainly something they shouldn't have been bothering you  with
in the first place.                   - Terry Pratchett, _Reaper Man_
