[Outreachy kernel] [PATCH v7 1/3] staging: rtl8723bs: Remove camelcase in several files

[Fabio M. De Francesco]

Remove camelcase in bFwCurrentInPSMode, a variable used by code
of several subdirectories/files of the driver. Issue detected by
checkpatch.pl. Delete the unnecessary "b" (that stands for "byte") from
the beginning of the name.

Signed-off-by: Fabio M. De Francesco <fmdefrancesco@gmail.com>
---

Changes from v6: Edit against the wrong patch (again).
Changes from v5: Edit against the wrong patch.
Changes from v4: Mention the removal of the initial "b" in log message.
Changes from v3: Fix errors in the format of the patch.
Changes from v2: Remove unnecessary comment. Shortened a function name.
Changes from v1: No changes to the code but only to the subject for the
purpose to differentiate this patch because other removes of camelcase
have been made in other files of the same directory.

[Outreachy kernel] [PATCH 4/4] staging: rtl8723bs: Change the type and use of a variable

[Fabio M. De Francesco]

Change the type of fw_current_in_ps_mode from u8 to bool, because
it is used everywhere as a bool and, accordingly, it should be
declared as a bool. Shorten the controlling
expression of an 'if' statement.

If this is only checked, how can it ever be true?  Who ever sets this

Why is there a "v7" in this subject line, but not all the other lines?

It should be in all of them, including the 0/X email, git format-patch
will create it automatically if you tell it to.

It's v7 because only this file (and not the others in the series had six 
previous versions that you dropped. Please remind that it was already sent 
alone (not in a series) several times. The changelog is in the body.

Should I drop that "v7" and the changelog, and the send the patch series 
anew?

Please, I'm waiting your instructions on what to do.

Thanks,

You're right. It is not set, therefore the "if" control expression cannot 
ever be "true".

Can I delete this statement in a new patch? Or you prefer I send the whole 
series again with this change in patch 4/4?

I think it's already updated everywhere with true and false, so there is
nothing to change.  But it would be good to make that clear in the log
message.

Julia, I'm a bit confused...

I've anew examined that line and noticed that fw_current_in_ps_mode is 
referenced by through a pointer returned by adapter_to_pwrctl(padapter). 
padapter is a pointer set in other files of the driver.

To me it seems that is perfectly reasonable that, as a result, 
fw_current_in_ps_mode could be set (externally) either with true or false.

I'm sure I'm missing something, since both you and Greg have a larger 
experience than I could ever have. Can you please elaborate this topic a 
bit more in order to make me understand whatever I can't see?

Thanks for your kind help,

Just delete the variable from the structure entirely and when it is
used.

It's a v2 series now, right?  :)

Don't "wait" for anyone, least of all me.  Do what you think is needed,
after waiting a bit of time, there's no rush here...

OK, I was just following my recollection of the code.  It seems that the
only thing that is needed is to explain in the log message how the
variable is initialized and why changing the type doesn't mean that you
have to change the initializations.  A weakness of the patch notation is
that you only see what changed, and not all of the code that is actually
relevant.  So if there is something that is not visible and that is
important to convince the reader that the change is correct, then it
should be mentioned in the log message.

Again, not having looked at the code, but does this pointer already have a
bool type?  Or does it have a u8 type?  Perhaps the pointer has to be
changed too?

I've read the code of the function whom that 'if' statement belongs to. 
This function takes a pointer whose name is 'padapter' and this is has 
global scope. I think that since fw_current_in_ps_mode is dereferenced by 
the function adapter_to_pwrctl(padapter) it can and is indeed initialized 
and modified in some other files of the driver.

That's why I'll leave the if statement as is now. If I am wrong there's 
time to change it later in a future patch.

Where does that happen, and why did the build not break when you changed
the variable name?  Is the whole variable assigned to a specific
location in memory in the device?  Where is it initialized?

Don't change obviously wrong code, we can clean it up properly :)

The build didn't break because I changed the name of that variable 
everywhere it is used in the driver. This patch is against all the affected 
files of each subdirectory of staging/rtl8723bs.

That variable has global scope and is assigned at least in:

drivers/staging/rtl8723bs/core/rtw_pwrctrl.c:368:                       
pwrpriv->fw_current_in_ps_mode = false;

drivers/staging/rtl8723bs/core/rtw_pwrctrl.c:380:                       
pwrpriv->fw_current_in_ps_mode = true;

drivers/staging/rtl8723bs/hal/rtl8723b_hal_init.c:433:  
adapter_to_pwrctl(padapter)->fw_current_in_ps_mode = false;

drivers/staging/rtl8723bs/core/rtw_pwrctrl.c:981:       
pwrctrlpriv->fw_current_in_ps_mode = false;

Right, and as you only had to change it in one place, that tested if
that variable was set to a specific value, and there is no code that
actually sets the variable, it seems like that variable is not ever used
and can be removed.

Ah, you are only changing the type, not the name.  That's the confusion
on my part.

Was the code setting a u8 to "true/false"?  Ugh, what a mess...

What do you mean by global scope?  None of the following look like

I just mean that fw_current_in_ps_mode is a field of a struct in a .h file 
included everywhere in this driver and that the functions whom the 
following assignments belong to have not the "static" type modifier.

OK, but a field in a structure is not a variable, and this is not what
scope means.

int x;

outside of anything is a global variable (global scope).

int foo() {
  int x;
  ...
}

Here x is a local variable.  Its scope is the body of the function.

int foo() {
  if (abc) {
    int x;
    ...
  }
}

Here x is a local variable, but its scope is only in the if branch.

And you're right again: I needed a little refresh of my knowledge of C.

I've searched again in the code for the purpose of finding out if that 
struct is initialized with global scope but I didn't find anything. I 
didn't even find any dynamic allocation within functions that returns 
pointers to that struct.

Therefore, according to Greg's request, I'll delete that stupid 'if' 
statement in the patch series v2 that I'm about to submit.

I've really appreciated your help.

I'm really not clear on why the if should be deleted.

I'm supposed to delete it because of the review made by Greg. In a couple

"If this is only checked, how can it ever be true?  Who ever sets this 
value?"

and then:

"Just delete the variable from the structure entirely and when it is
used.".

However, like you, I'm not sure yet.
