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
clk: sunxi: clk-usb: Demote obvious kernel-doc abuse
clk: tegra: clk-tegra30: Remove unused variable 'reg'
clk: clkdev: Ignore suggestion to use gnu_printf() as it's not
appropriate here
clk: tegra: cvb: Provide missing description for
'tegra_cvb_add_opp_table()'s align param
clk: ti: dpll44xx: Fix some potential doc-rot
clk: renesas: renesas-cpg-mssr: Fix formatting issues for
'smstpcr_saved's documentation
clk: sunxi: clk-sun6i-ar100: Demote non-conformant kernel-doc header
clk: qcom: gcc-ipq4019: Remove unused variable 'ret'
clk: clk-fixed-mmio: Demote obvious kernel-doc abuse
clk: clk-npcm7xx: Remove unused static const tables 'npcm7xx_gates'
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
'flags'
clk: qcom: clk-rpm: Remove a bunch of superfluous code
clk: spear: Move prototype to accessible header
clk: imx: Move 'imx6sl_set_wait_clk()'s prototype out to accessible
header
clk: zynqmp: divider: Add missing description for 'max_div'

No. That would make the whole clean-up process 10x harder than it
already is
Before starting this endeavour there were 18,000+ warnings spread over
100's of files and 10's of subsystems that needed addressing (only a
couple thousand left now thankfully). Some issues vastly different,
some duplicated (much too much copy/pasting going which made things
very frustrating at times).
Anyway, in order to work though them all gracefully and in a sensible
time-frame I had to come up with a workable plan. Each subsystem is
compiled separately and a script attempts to take out duplicate
warnings and takes me through the build-log one file at a time. Once
all of the warnings are fixed in a source-file, it moves on to the
next file. The method is clean and allows me to handle this
gargantuan task in bite-sized chunks.
Going though and pairing up similar changes is unsustainable for a
task like this. It would add a lot of additional overhead and would
slow down the rate of acceptance since source files tend to have
different reviewers/maintainers - some working faster to review
patches than others, leading to excessive lag times waiting for that
one reviewer who takes weeks to review. Having each file addressed
in a separate patch also helps revertability and bisectability. Not
such a big problem with the documentation patches, but still.
Admittedly doing it this way *can* look a bit odd in *some* patch-sets
when they hit the MLs - particularly clock it seems, where there
hasn't even been a vague attempt to document any of the parameters in
the kernel-doc headers - however the alternative would mean nothing
would get done!

Out of interest, what normally happens to the patches which aren't
picked up by individual driver Maintainers?

I mean, you have literally used the same commit log and the same changes
over six different files in the same directory. Sure changes across
different parts of the kernel can be painful, but it's really not what
we're discussing here.

Are you arguing that sending the same patch 6 times is easier and faster
to review for the maintainer than the same changes in a single patch?

There's nothing to revert or bisect, those changes aren't functional
changes.

Yeah, and even though properly documenting the functions would have been
the right way to fix those warnings, I didn't ask you to do that since I
was expecting it to be daunting. Surely we can meet half-way

Yes, that happens. It's an unfortunate side-effect of the same ol'
issues repeating themselves over and over. Mostly due to copy/paste
of mundane code segments such as function documentation.

It would have even been painful to post-process patches within the
same subsystem. For instance, I've just finished cleaning up GPU
which was a mammoth task where most of the issues were perpetually
duplicated.
I will admit though, that here in Clock, it would be somewhat easier.

The issue I see with the Clock, is that some files are maintained by
individual driver Maintainers and others by subsystem Maintainers. So
the post-process here is that much more painful (as it can't be
easily scripted using get_maintainer.pl) and the aforementioned
lag-time issues come into play while we wait for sleepy reviewers.

There are a couple of schools of thought on function documentation.
The conflicting one to yours is that Kernel-doc headers should only be
used if they are part of an API and have an accompanying kernel-doc::
tag in Documentation. The functions touched here do not.
NB: Fortunately the functions we're discussing are all static or else
`scripts/find-unused-docs.sh` would complain about them also.
Personally, I am in the middle. If authors have had a good go at
documenting functions and their parameters, I'll make the effort to
fix any doc-rot or oversights. However if, like here, no such effort
has been made, they get demoted. Nothing stopping authors fixing them
up properly and re-promoting them again though. Essentially I'm
trying to avoid a situation where authors throw something together
half-heatedly, safe in the knowledge that someone will come fix and
beautify things for them.

I'm always happy to collaborate. What does half-way look like?

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.

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.

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.

That makes sense. Thank you for the explanation.
