Line too long.  No blank.  Fix indenting.

It's not really clear what you're trying to do actually...  You need to
sell your patch a bit to try convince us that it's worth applying.

I feel like you need to break the patch up a bit and do the white
space fixes separate from the other changes.

(Probably you're going to have to redo this several times because it's
hard to review when it's so mixed up with multiple changes at the same
time).

Hi Dan,
Thanks a lot for your feedback, this is my first patch for the linux kernel
so I'm learning a lot from your comments.

I'll try to make a more clear version of the patch following your
suggestions
to resubmit.

Best,
Dante Paz

But it raised a few comments.

The staging/fbtft is a dumping of a set of drivers that
in the end will be migrated to DRM.
And there is not much gained trying to do coding style changes to these
drivers.
So please conmsider finding a drver where this is more relevant.

Furthermore that patch presented is hard to review as it contains
too much changes in one go.
As a rule of thumb include only one type of change per patch.
This is worth to keep in mind for future submissions.

It it then also good to present the trivial changes first(*), and the
less trivial changes later.

(*) Like whitespace to tabs, spellign errors etc.

Hello Sam, thank you very much for your comments,
As I told Dan (my email did not reach the mailing list) this is my
first attempt to contribute,
So I'm learning a lot from your advice and corrections.

I will look for TODO lists to see if there are more useful
contributions to make, all suggestions are also welcome.

Thanks again for the patience of all of you.
Best,
Dante

Hi everyone,

Dante: please avoid top-posting. In other words, put your replies in-line,
like I'm gonna do now. See below (and see how discussion goes on other threads).

Sam,

Why is this driver still here? I thought we migrated everyhing to
tinydrm already.

Maybe there's a list of panels still not migrated?

Hi Eze

Some have been ported, some are waiting for a user to do the port.
If you looks at tinydrm you will see:
ili9225.c  ili9341.c

And we also have under panel:
panel-ilitek-ili9881c.c
panel-ilitek-ili9322.c

But in staging there are more panels than just these.

So we have not yet ported all.
And there is today no list of what is missing.

Keep the good spirit, and find some other driver to look into.

You must realise than experienced developers sometimes goes
through several version before a patch is ready.
So expect it to be a bumpy ride the first few times.

Good luck!

Right.

Perhaps the TODO file on fbtft should be updated stating clearly that
we don't care about cleaning this one.
This is important given staging is used for Outreachy and other
introductory programs.

We can also add some big fat warning message (in case there isn't one
already) asking users of staging/fbtft to help porting/testing the
port to tinydrm.

Thanks,
Eze
