Not related to your patch, but this check makes no sense.  The
rtw_free_mlme_priv_ie_data() function dereference pmlmepriv
unconditionally so it would have already crashed.

Formally, you are removing the wrapped functions (or helpers, if you 
prefer) by moving their code into the wrappers. To say that you are 
removing the wrappers is not correct.

However, I'm sure this kind of formal mistake won't prevent your patches
to be accepted. I wanted to point this out to you in case you decide to 
submit similar patches in the future and perhaps want to describe your 
changes a little more accurately.

I once had someone make me re-write a commit message four time just as a
kind of bullying and then at the end he was like, "You said NULL
dereference instead of NULL pointer dereference so I had to re-write the
commit message and I added some comment to the kernel git log explaining
how you suck."  So these days I have made it a rule that if you're going
to complain about commit messages then you have to write your own for
people to cut and paste.  Otherwise people are like, "You're too stupid
to read my mind.  LOL.  Do it again."

But in this case the commit message is fine.  The key things with a
commit message are:

1) What's the motivation
2) What's the effect for the user
3) Are all the surprising aspects are explained.  Do I have enough
   information to review it quickly.

Removing wrappers is the motivation.  No need to explain that further.
No effects for the user.
There were no surprising bits.

It's fine.

I'm assuming you don't believe that I attempted some kind of bullying similar
to what you had to face when you sent the above-mentioned patch.

Nevertheless, I was expecting some sort of reaction from you but I think 
that you are misunderstanding what my intentions were.

I didn't suggest a re-write of the commit messages. I just pointed out that 
those messages are formally inaccurate but that these kinds of small formal 
inaccuracies won't ever prevent Vihas' patches from being accepted as they are.

It's only that, IMO, if people start to take care of being formally correct 
in drivers/staging, even when they do simple changes, they train their minds
to improve their abilities to communicate in the future when they eventually
decide to submit much more complex patches in other subsystems.

I agree with you: "it's fine". I respect your opinion and your pragmatism:
after all, here, everything is pretty clear, so why bother?

However, writing accurate and formally correct commit messages takes the 
same amount of time of writing inaccurate messages. So, why not do better 
next time?

Again, I don't suggest to do so now. Not for these patches, because it would 
only be a loss of precious time.

Yes.  That's the problem.  If you want to complain about a commit
message then you *should* suggest how you would re-write it.  Otherwise
how are we supposed to read your mind?

> I just pointed out that those messages are formally inaccurate but

I'm so puzzled but what you mean here.  There were no "small formal
inaccuracies".  The patch removed unnecessary wrappers exactly as
described.  Anyway, I haven't seen your proposed commit message so I
can't say.

Ah, sorry. I had missed that you were asking for a re-write (literally).

Here it is a sort of diff on Vihas' patch:

- [PATCH v2 1/7] staging: r8188eu: drop unnecessary wrapper _rtw_free_cmd_priv
+ [PATCH v2 1/7] staging: r8188eu: drop unnecessary helper _rtw_free_cmd_priv()

- Drop unnecessary wrapper _rtw_free_cmd_priv and move its logic to
- rtw_free_cmd_priv.
+ Drop unnecessary helper (wrapped function) _rtw_free_cmd_priv() and
+ move its code to the wrapper rtw_free_cmd_priv().

I kind of feel like the original is better.  Why would we want to remove
helper functions?  Helper functions are ok.  What we don't like are
pointless wrapper functions.  The whole motivation for the patch is to
remove wrapper functions and that's what it does.

Are you also talking about re-sending patches for media/atomisp? I 
submitted three patches for that driver between April 8-12. They have 
already been reviewed and tested by Ira Weiny and Hans de Goede.

However, if I remember correctly, they should take a different path and it 
should be up to Mauro C. Chehab to apply them. Do you want them to be sent 
again?

Heh.  No.  No one was discussing your patches or anything to do with
media.  These are for staging: r8188eu.

Dan, got it now :)

I was confused by Greg's words talking about "My queue of staging..." . Now 
you confirm that media/atomisp has never been in his queue.
