[PATCH v2] staging: sm750: Rename function to avoid CamelCase

[PATCH v2] staging: sm750: Rename function to avoid CamelCase

[Kloudifold]

The sm750 driver had some functions named in CamelCase,
which violates the kernel's naming convention.
In this patch, I rename these functions to snake case,
which is the expected style.

This v2 patch was prompted by an error reported by the
Linux test robot, which detected the compile error.

Please go back and read the Outreachy tutorial, specifically the Patch
Philosophy page:

https://kernelnewbies.org/PatchPhilosophy

The log message should be in the imperative.  You should try to avoid the
use of "I".  "In this patch" is not necessary.  Mentioning the name of the
driver is not necessary, since it appears in the subject line and in the
list of changed files below.

This is not easy to understand.  What do you mean by a compile error.
Normally the use or non use of Camel case would be a coding style
violation, but would not provoke a compiler error.

Hi,
please make the Subject more unique. Many patches could have this name.
Look for examples in:
https://lore.kernel.org/linux-staging/

Please use your full name consisting of a given name and a family name 
in front of your email. Or is this not possible and "Kloudifold" is both?

Kloudifold,

It'll probably take a bit for the change, allowing pseudonyms, to become
common knowledge. When the question comes up, you can just point to the
latest update to Documentation/process/submitting-patches.rst as I've
done below.

Phillip,
I commented similar to you, and then discovered this:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d4563201f33a022fc0353033d9dfeb1606a88330

Pseudonyms now allowed.

"Known pseudonyms" are now allowed.  So that means that somehow I need
to "know" this is actually a pseudonym and that it is unique and so on.
As you are dealing with outreachy already, odds are you have to use a
non-pseudonym for them in order to track patches and payments and the
like, so please use the identifier you use with outreachy.

thanks,

Hi,

I'd like to write the patch description as (ignore markdown):

```
sm750 driver has sm750_hw_cursor_* functions, which are named in
camelcase. Rename them to snake case to follow the function naming
convention.

Fixes: <commit that introduces these camelcase function>
```

Thanks.

Why are you asking for a Fixes tag on this? 
Seems unusual for a staging driver cleanup.

I thought this style cleanup also warrants Fixes: since
it fixes coding style problem on existing code (see
Documentation/process/submitting-patches.rst).

No, sorry, Fixes: is for real bugs, not style issues.

The tags from lkp go with your tag below - 

  Reported-by: kernel test robot <lkp@intel.com>

Your next changelog, will look something like this:

Changes in v3:
- Add this changelog (Philipp)
- Move lkp tags and link to the correct location in commit log (Alison)
- Update the commit msg (Philip)
- Update the commit log (Bagas, Julia)

Changes in v2:
- Use new function names in call sites (LKP)



Khadaji,
Did you see the compile errors?  What was the deal with that?
Thanks,
Alison

Re: [PATCH v2] staging: sm750: Rename function to avoid CamelCase

[Kloudifold]

Hi Alison,

Thanks a lot for your help, so if I send my v3 patch, should it be like
below? (Philipp said "please make the Subject more unique", but the
Subject could be only a few permutations of very few words, I can't see
how it could be any more unique.)

Subject: [PATCH v2] staging: sm750: Rename functions from CamelCase to snake case

sm750 driver has sm750_hw_cursor_* functions, which are named in
camelcase. Rename them to snake case to follow the function naming
convention.

Changes in v3:
- Add this changelog (Philipp)
- Move lkp tags and link to the correct location in commit log (Alison)
- Update the commit msg (Philip)
- Update the commit log (Bagas, Julia)

Changes in v2:
- Use new function names in call sites (LKP)

All these changes should go below the --- line, not above it like this.
The history of changes is for people who are following along in the email
discussion.  Once the patch is accepted, they won't be meaningful.  So
they should be the in the part that disappears, which is the part below
the ---.

You may want to review similar patches submitted in the past by the developers
and get hints on how it was named then. Use it to improve your understanding,
let your own thoughtfulness prevail.

If I only see the subject above, which functions are renamed? I have
to see the actual diff if the patch description doesn't answer that.
In this case, I think the proper subject would be `[PATCH v3] staging:
sm750: Rename sm750_hw_cursor_* functions to snake_case`.

kernel test robot (lkp) reported errors on your submitted patch, not
on commits already in the tree, so both Reported-by: and Link: trailers
above are not appropriate.

If you want to add trailers from someone else (like kernel test robot
above), you just need to write e.g. (ignore markdown):

```
Link: <link>
Reported-by: <identity>
Tested-by: <identity>
```

In other words, trim the preceding ``| ``.

See you in v3!
