[PATCH 0/6] thermal: Align devm_thermal_zone_{device,of_sensor}_register

[PATCH 0/6] thermal: Align devm_thermal_zone_{device,of_sensor}_register

[Marek Vasut]

This patchset attempts to align devm_thermal_zone_{device,of_sensor}_register()
functions and allow passing tz params to devm_thermal_zone_of_sensor_register()
to allow settings no_hwmon params without digging into the tz structures.

The approach is as follows:
1) Add {devm_,}thermal_zone_of_sensor_register_params(), which behaves just
   like the old variant without _params() suffix, except it takes the struct
   thermal_zone_params as an argument. The old _params()-less version of the
   function is converted to use the new function and pass params = NULL.
   The old _params()-less versions of the functions are retained to avoid
   breaking the ABI.
2) Add the no_hwmon handling into thermal_zone_of_sensor_register_params(),
   that's patch 3.
3) Convert drivers from devm_thermal_zone_of_sensor_register() with structure
   diggings to devm_thermal_zone_of_sensor_register_params() without any
   extra structure digging, that's the rest of the patches.

[PATCH 1/6] thermal: split thermal_zone_of_sensor_register{,_param}()

[Marek Vasut]

Introduce new thermal_zone_of_sensor_register_params() function, which
allows passing struct thermal_zone_params into it and convert original
thermal_zone_of_sensor_register() to call it with params set to NULL.

I recall a discussion about gmail stripping the +foo tags from email
addresses. I can add a From: tag into the patch to override this
braindeath, or is there a better solution ?

Run the "git format-patch" command from a git repo where user.email
is marek.vasut@gmail.com, so it will retain the original From: tag in the
email body, as it is different?

I can also manually patch the From tags or add them, but it's all
workarounds.

Or maybe it'd make sense to fix git to handle the +tags correctly ?

What needs to be fixed?
If user.email != From, git format-patch generates a From: header, else
it doesn't. Doesn't that make sense?

I believe the complaint here is that email address in From does not
match email address in SoB line, because some SMTP servers scrub the
+foo tag from From: and not from SoB-line . And yet, the SoB line is
from the same person/email address as the email address in From, so they
are equal. I think git should just ignore the +foo tag in SoB line.

Some SMTP servers (Hi Gmail!) scrub the +foo tag from the From: _header_
in the email. As the SoB is in the _body_ it is not affected.
Hence the solution is to include the correct From: in the _body_.

Git actually does that automatically, assumed your user.email config matches
the From: address that is used in your outgoing email delivery path (i.e. the
scrubbed one, when using Gmail's SMTP server).
If you lie to git in your user.email config, git cannot do the right
thing, obviously.

> from the same person/email address as the email address in From, so they

If they differ, they are not equal ;-)
While many mail servers ignore +foo when delivering email to mailboxes,
this is not the case for all of them.  So ignoring +foo is not the universal
solution.

> I think git should just ignore the +foo tag in SoB line.

Where should "git" ignore the +foo tag? Is it actually git that complains?
Eduardo: Do you mean checkpatch? ;-)

I did enhance checkpatch with a check to verify that patches carry SoB tags
from their authors, as too many people got that wrong, causing complaints
from sfr in linux-next later. As usual, it's better to get things right as early
as possible in the process, to avoid rework.

So the problem is on the patch sending side, not on the patch verification
receiving side.
Hence please fix your email setup, thanks!

This is basically what I said.

My git user.email obviously matches the From: field , before the
scrubbing, which I believe is the correct thing to do.

Depends on how you define 'equal' . Here I think foo+bar@example.com
should be considered equal to foo@example.com .

Possibly. I ran checkpatch after git format-patch and it didn't complain.

Aha, so maybe that enhancement needs further enhancement to scrub the
+tags before the check ?

I disagree, because that is not how the emails are actually going out from the

According to git-send-email(1), you can either pass your scrubbed email
address to --from, or configure it in the sendemail.from config option.
Does that work for you?

In general, you cannot assume the "+foo" part can be ignored. Only the sender
knows.

So sendemail.from != user.email , the later has the +tag while the
former does not ?

It depends on the domain.

Is Bill.Gates@microsoft.com the same email address as
Bill.Gates+foo@microsoft.com?
Is Bill.Gates+1955@microsoft.com the same?
Is Bill.Gates-1955@microsoft.com the same?

I don't know. Only microsoft.com knows.
So that's why you should compare email addresses verbatim (but case
insensitive).

Oh, you mean email-domain. In that case, since gmail treats
foo@gmail.com the same as foo+bar@gmail.com , checkpatch should treat
them equally as well. In which case, your checkpatch patch which now
generates a warning on this is wrong ?

So checkpatch should know about all email domains?

Just fix your setup. All patch statistics operate on the author, incl. +foo, so
your patches will be attributed wrongly.

If correct handling is domain specific knowledge, as you just said,
apparently so. Otherwise checkpatch produces false positives.

Well your suggestion with sendemail.from doesn't seem to change
anything, but I'll keep it in.

Are you serious?

Even with gmail, some companies may use a single gmail account for public
development, and use the +foo to distinguish between individual developers.
So you cannot ignore it.

Hm, that's a rather warped example, but I guess one can use it like so.

[PATCH 2/6] thermal: split devm_thermal_zone_of_sensor_register{,_param}()

[Marek Vasut]

Introduce new split:devm_thermal_zone_of_sensor_register_params()
function, which allows passing struct thermal_zone_params into it
and convert original devm_thermal_zone_of_sensor_register() to call
it with params set to NULL.

[PATCH 3/6] thermal: Register hwmon in thermal_zone_of_sensor_register_param()

[Marek Vasut]

Register hwmon sysfs interface in thermal_zone_of_sensor_register_param()
in case thermal_zone_params->no_hwmon is set to false. This behavior is
the same as thermal_zone_device_register().
