This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

This is the last set.  Clock is clean after this.

Lee Jones (21):
  clk: zynq: pll: Fix kernel-doc formatting in 'clk_register_zynq_pll's
    header
  clk: ti: clkt_dpll: Fix some kernel-doc misdemeanours
  clk: ti: dpll3xxx: Fix some kernel-doc headers and promote other
    worthy ones
  clk: qcom: clk-regmap: Provide missing description for
    'devm_clk_register_regmap()'s dev param
  clk: sunxi: clk-sun9i-core: Demote non-conformant kernel-doc headers

    and 'npcm7xx_divs_fx'
  clk: qcom: mmcc-msm8974: Remove unused static const tables
    'mmcc_xo_mmpll0_1_2_gpll0{map}'
  clk: clk-xgene: Add description for 'mask' and fix formatting for

Is it possible to slam in some patch that makes W=1 the default for the
clk directory? I'm trying to avoid seeing this patch series again.

One of my main goals of this project is that everyone (contributors,
maintainers auto-builder robots etc) will be enabling W=1 builds
*locally*.

This isn't something you'll want to do at a global (i.e. in Mainline)
level.  That's kinda the point of W=1.

Agreed, but is it possible to pass W=1 in the drivers/clk/Makefile?

That would circumvent the point of W=1.  Level-1 warnings are deemed,
and I'm paraphrasing/making this up "not worth rejecting pull-requests
over".  In contrast, if Linus catches any W=0 warnings at pull-time,
he will reject the pull-request as 'untested'.

W=1 is defiantly something you'll want to enable locally though, and
subsequently push back on contributors submitting code adding new
ones.

Why should I install a land mine for others to trip over? Won't that
just take them more time because they won't know to compile with W=1 and
then will have to go for another round of review while I push back on
them submitting new warnings?

The alternative is to not worry about it and review the slow drip of
fixes that will occur as a result.  The issues I just fixed were built
up over years.  They won't get to that level again.

In my mind contributors should be compiling their submissions with W=1
enabled by default.  I'm fairly sure the auto-builders do this now.

Once W=1 warnings are down to an acceptable level in the kernel as a
whole, we can provide some guidance in SubmittingPatches (or similar)
on how to enable them (hint: you add "W=1" on the compile line).

Enabling W=1 in the default build will only serve to annoy Linus IMHO.
If he wants them to be enabled by default, they wouldn't be W=1 in the
first place, they'd be W=0 which *is* the default build.

Just to add real quick - my advice is to enable them for yourself and
send back any issues along with your normal review.  A W=1 issue is no
different to a semantic or coding style one.

I'd like to enable it for only files under drivers/clk/ but it doesn't
seem to work. I'm not asking to enable it at the toplevel Makefile. I'm
asking to enable it for drivers/clk/ so nobody has to think about it now
that you've done the hard work of getting the numbers in this directory
down to zero or close to zero.

I'm not sure which one of us is confused.  Probably me, but ...

Even if you could enable it per-subsystem, how would that help you?

How can you ensure that contributors see any new W=1 warnings, but
Linus doesn't?  When Linus conducts his build-tests during the merge
window, he is also going to build W=1 for drivers/clk.

All that's going to achieve is put you in the firing line.

From my PoV W=1 builds should be enabled during the development phase
(i.e. contributor, auto-builder, maintainer).  By the time patches get
make it into Mainline the review/testing stage is over and only the
default W=0 warnings are meaningful.

The assumption is contributors would have compiled the code they're
sending, but that's obviously not always the case, so this assumption
relies on developers running make. If they do run make then the hope is
they would see the warnings now, without having to rely on them to know
about passing W=1 to make, and fix them before sending code. If
developers are ignoring build errors or warnings then we can't do
anything anyway.

Ok. Is this prior experience?

Alright maybe I don't understand and W=1 builds are noisy for the
drivers/clk subdirectory even after applying these patches. Or it has
some false positives that won't be fixed? Or a new compiler can cause
new warnings to happen? I could see these things being a problem.

I'm trying to see if we can make lives better for everyone by exposing
the warnings by default in the drivers/clk/ directory now that there are
supposedly none left. Shouldn't we tighten the screws now that we've
cleaned them?

About a cycle ago, Arnd and i played around with this idea. The
Ethernet PHY subsystem is W=1 clean, and most of he network stack
is. But keeping it clean is not so easy, when developers do sometimes
add new warnings, since they have no idea the code is W=1 clean.

You are also not the only one asking for such a feature. RDMA also
asked recently.

Arnd, do you plan to push the patches?

Do you use patchwork? netdev has a bot attached which applies the
patch and does a W=1 build, and will report any new warnings. But it
does not email the developer, as far as i know. It is up to you as the
maintainer to reject the patch and say why.

Compare this with for example:

Thanks for this.

Oh, I see.  So you conduct tests locally, then post them up in a
section called 'Checks' using the provided API.  I assume that
Patchwork does not alert the user when something has gone awry?  Is
this something Nipa does?

For some definition of "locally" - NIPA runs on a rented VM.

The way we run it on netdev is maintainer-centric, IOW we see 
the failures in patchwork and complain to people manually.
The netdev mailing list gets too many messages as is, if NIPA 
responded with results automatically (which is not that hard
technically) my concern is that people would be more likely to
send untested patches to the mailing list and rely on the bot.

Right.  Infrastructure that you control vs by Patchwork.
