linux-next: build failure after merge of the pinctrl tree

Hi all,

After merging the pinctrl tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/pinctrl/mediatek/pinctrl-mt6779.c:783:1: warning: data definition has no type or storage class
  783 | arch_initcall(mt6779_pinctrl_init);
      | ^~~~~~~~~~~~~

  779 | static int __init mt6779_pinctrl_init(void)
      |                   ^~~~~~~~~~~~~~~~~~~

Caused by commit

  e6f744c6ad4f ("pinctrl: mediatek: add pinctrl support for MT6779 SoC")

Forgot to include module.h (since it is tristate in Kconfig) or init.h?

I used the pinctrl tree from next-20200716 for today.

My fault, I'll fix it in next version.

OK I pulled out all the MTK6779 patches from my tree and wait
for a new version.

Ah I forgot a prerequisite patch we postponed before.

Applied it now so things should work by tomorrow, thanks!

I was test it that base on 6.1-rc3 master branch and it is okay, but in 
pinctrl tree test that need include following head file.

How typical, the ideal way to resolve it is if there is an immutable
branch with the
basic changes I can pull in from the i2c tree and apply Stephen's fix on top,
or we can just wait for the merge window and let Torvalds sort it out?

It is already there:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/make_remove_callback_void-immutable

Uwe (originator of the series) spread this information. Sorry that it
did not reach you.

Oh excellent, pulled this in and applied Stephens fixup on top.

Don't worry about that, there is no perfect process.

Ideally you would have squashed the fixup into the merge commit. With
the history as it is now you introduced a commit (i.e.  1681956cb79c
("Merge branch 'i2c/make_remove_callback_void-immutable' of
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux into devel"))
that fails to compile the pinctrl-cy8c95x0 driver. Also a better subject
line than "pinctrl: fixup for "i2c: Make remove callback return void""
would be nice, I would have mentioned 'cy8c95x0' at least. (But this is
mood of course if your tree is already stable or you remerge and
squash.)

This commit touches quite a lot of files and subsystems. In the first
revision I added all affected maintainers and lists. vger refused the
mail because the the headers got too long.

Best regards
Uwe

linux-next: build failure after merge of the pinctrl tree

Hi all,

After merging the pinctrl-samsung tree, today's linux-next build
(x86 allmodconfig) failed like this:

The tegra_pinctrl_get_group() should return const and not cast the
pointers. Please make another patch to fix it properly.

Instead of returning const pointer from tegra_pinctrl_get_group()
the return value is being casted.

This change helps return const pointer.

linux-next: build failure after merge of the pinctrl tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 312 bytes --]

Hi all,

After merging the pinctrl tree, today's linux-next build (x86_64
allmodconfig ) failed like this:


Presumably caused by commit

  c9e84d46cc03 ("pinctrl: rockchip: make driver be tristate module")

I have used the pinctrl tree from next-20210303 for today.

Sorry I lost the error message, but it was a reference to a symbol that
has no EXPORT_SYMBOL.  So building the driver as a module should show
the error.

Sorry for the mess, I dropped this commit now.

I think we need a separate patch to export that call

linux-next: build failure after merge of the pinctrl tree

I'm the first user of this function within a driver and the functions
lacks of EXPORT_SYMBOL_GPL() currently.

@Linus
Shall I send a patch to address this or do you prepared a patch already?

The bug you are referring to is in the gpio tree, not pinctrl.
That had me confused for a while, and is the reason I'm writing
this. Maybe the next person need not be confused...

But when I'm writing on this topic anyway, I'll add some more
info, in case anyone cares.

I think fix for this bug is to use gc->irq_chained_parent instead
of gc->irq_parent, at least that changed as part of the indicated
commit. Completely untested...

The fix for the bug in the pinctrl tree is to add a missing >
as posted by Andrew Lunn in [1] (with a slightly broken commit
message; two counts of s/chip-/client-/, an extra line after
the sob and I guess the subject is no longer true).

Cheers,
Peter

Part of the gpio tree has been merged into the pinctrl tree (see commit
70afa835d2d7 ("Merge branch 'thread-irq-simpler' of /home/linus/linux-gpio
into devel")), but when I merge the gpio tree later in my process, I do
not get this error.

Thanks for the info ... this still needs fixing in the pinctrl tree.

Right. *blush*

The reason appears that the gpio tree has updates to the pl061 driver
that is not present in pinctrl, specifically
009df9a02000 ("gpio: pl061: use local state for parent IRQ storage")

I guess you could merge gpio first, but you'd still hit the silly bug
in pinctrl that Andrew fixed so maybe that's not worth it...

Sorry. My intention was of course to put the required pl061 patches on
an immutable branch and pull into pinctrl as well.

Oh well.

I cannot figure out what caused it, but using the pinctrl tree from

I am using gcc 5.2.0 hosted on powerpcle, if that matters.

Re: linux-next: build failure after merge of the pinctrl tree

[Linus Walleij]

Laxman, this must be due to one of the two top commits for tegra:

commit 1d18a3f0f0809f6c71f1f6e9e268ee904ce0b588
"pinctrl: tegra: avoid parked_reg and parked_bank"
commit b22ef2a0979f2b91cfeeabb086e4d665183a93a1
"pinctrl: tegra: Correctly check the supported configuration"

Is it something you can fix quickly or should I just revert both patches
for the time being?

linux-next: build failure after merge of the pinctrl tree

[Stephen Rothwell]

Hi Linus,

After merging the pinctrl tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/pinctrl/bcm/pinctrl-iproc-gpio.c:640:50: warning: 'struct cygnus_gpio' declared inside parameter list

Caused by commit

 afc8c78d179d ("gpio: Rename func/macro/var to IP-block,iproc")

This does not look like it has even been build tested :-(

I have used the pinctrl tree from next-20151217 again as the previous
(fixed) error was hiding this one.

Hi Stephen/Linus,

The patch " [PATCH v2 5/7] gpio: Rename func/macro/var to IP-block,iproc" 
(https://lkml.org/lkml/2015/11/18/1004) in "for-next" and "devel" of  pinctrl
tree ( http://git.linaro.org/people/linus.walleij/linux-pinctrl.git ) has little rebase issue.

Original patch has:
<snip>
-static void cygnus_gpio_unregister_pinconf(struct cygnus_gpio *chip)
+static void iproc_gpio_unregister_pinconf(struct iproc_gpio *chip)
<snip>

while "for-next" and "devel" branch of pinctrl tree has:
<snip>
-static void cygnus_gpio_unregister_pinconf(struct cygnus_gpio *chip)
+static void iproc_gpio_unregister_pinconf(struct cygnus_gpio *chip) 
<snip>

Please suggest us how could we fix this issue.

I think you issue is different from what I reported, What I reported
was caused by the addition of the dependency on COMPILE_TEST which
allowed the driver to be built on architectures/platforms that do not
have the needed definitions.

Hi Stephen,

The issue I pointed out is the relevant and is fully related to the statement-

" After merging the pinctrl tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:"

Even I tried the build for config "arm multi_v7_defconfig" it was compile failed. After fixing this I see compilation successful. I don't think we see any more issue after this fix.

Please let me know in case I should try any more compilation.

Regards,
Pramod

Re: linux-next: build failure after merge of the pinctrl tree

[Ray Jui]

Hi All,

Yes I also checked the original patch that Pramod sent out:

@@ -636,13 +638,13 @@ static int cygnus_gpio_register_pinconf(struct 
cygnus_gpio *chip)
  	return 0;
  }

-static void cygnus_gpio_unregister_pinconf(struct cygnus_gpio *chip)
+static void iproc_gpio_unregister_pinconf(struct iproc_gpio *chip)
  {
  	if (chip->pctl)
  		pinctrl_unregister(chip->pctl);
  }

Somehow it was not merged properly into Linus' tree? The fix is simple 
and just like Pramod proposed.

Linus, how do you want to proceed with this?

Thanks,

Ray

Hi Linus,

After merging the pinctrl tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Grr a bad cherry-pick from my side. I've fixed it up today.

Hi Linus,

After merging the pinctrl tree, today's linux-next build (x86_64
allmodconfig) failed like this:

sound/soc/fsl/eukrea-tlv320.c:28:28: fatal error: asm/mach-types.h: No such file or directory
 #include <asm/mach-types.h>
                            ^

Probably caused by commit 6bca8471566c ("pinctrl: select dependency on OF
for MSM driver").  the build of eukrea-tlv320.c depends on CONFIG_OF
which is not normally set for as x86_64 build, but the above commit
caused it to be selected (I think).

I have used the pinctrl tree from next-20131206 again.

It turns out that this is build failure is actually caused by a commit in
the sound-asoc tree (436aa86f0414 "ASoC: eukrea-tlv320: Add DT support"),
but was exposed by the pinctrl tree commit.

So I am not sure if the pinctrl tree needs fixing (I think it did select
CONFIG_OF where it would normally not be).

It is trying to include an ARM-only file in an x86_64 compile...
I think the Kconfig for that driver needs a

depends on ARM

This doesn't repro for me with tegra_defconfig, which has both
CONFIG_PINCTRL and CONFIG_OF enabled.

I believe this happens because of the following in
drivers/pinctrl/Makefile:

obj-$(CONFIG_OF)		+= devicetree.o

On ppc64, CONFIG_OF is probably true, yet the rest of PINCTRL isn't
enabled, hence the headers that are included probably don't declare
all the types needed to compile that file.

In fact, the file shouldn't be compiled, since it's not needed if
!CONFIG_PINCTRL. So perhaps the Makefile should be more like:

ifeq ($(CONFIG_OF),y)
obj-$(CONFIG_PINCTRL)		+= devicetree.o
endif

(I see something similar to that in drivers/mmc/host/Makefile)

But, I notice the same construct in ./drivers/regulator/Makefile, and
I don't believe regulators are enabled for ppc64. Perhaps the
regulator headers always declare the types, so the issue doesn't come
up, although I daresay that perhaps the regulator file also shouldn't
be compiled when CONFIG_REGULATOR is off?

Easiest fixed with a new Kconfig like CONFIG_PINCTRL_OF that
depend on both right?

I'll cook a patch.

I don't think so; why wouldn't pinctrl automatically have DT support
when both pinctrl and OF are enabled. BTW, I already posted a patch to
fix this last week.
