Hi all,

After merging the irqchip tree, today's linux-next build (htmldocs)
produced this warning:

Hmmm... I've had a fix for this sitting in irqchip-fixes for some
time. But I now realise that this branch is not included in -next
while tip tracks it.

Any chance you could add [1] to -next in the future?

Thanks,

So I assume this a branch of bug fixes for the current release, right?
In which case I will add it tomorrow.

Yes, that's exactly what this is.

Added from today.

Thanks for adding your subsystem tree as a participant of linux-next.  As
you may know, this is not a judgement of your code.  The purpose of
linux-next is for integration testing and to lower the impact of
conflicts between subsystems in the next merge window. 

You will need to ensure that the patches/commits in your tree/series have
been:
     * submitted under GPL v2 (or later) and include the Contributor's
        Signed-off-by,
     * posted to the relevant mailing list,
     * reviewed by you (or another maintainer of your subsystem tree),
     * successfully unit tested, and 
     * destined for the current or next Linux merge window.

Basically, this should be just what you would send to Linus (or ask him
to fetch).  It is allowed to be rebased if you deem it necessary.

Huhuh... This patch should have never made it in -next. I must have
messed up once more.

/me goes and rebuild the branch now, which will also get rid of the
fixups lacking SoBs.

Thanks for the heads up,

linux-next: build warning after merge of the irqchip tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1265 bytes --]

Hi all,

After merging the irqchip tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

In file included from include/linux/io.h:25,
                 from include/linux/of_address.h:7,
                 from drivers/irqchip/irq-imx-gpcv2.c:9:

   ^~~~

Introduced by commit

  ed01edc0ab6f ("irqchip/irq-imx-gpcv2: Add support for i.MX8MQ")

This is caused by my use of -Wimplicit-fallthrough for Kees Cook.

Replacing the "/* FALLTHROUGH */"  with "/* fall through */" but on the
line above will suppress the warning.

I've now pushed out a patch that does exactly that. Thanks for

linux-next: build warning after merge of the irqchip tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 749 bytes --]

Hi Jason,

After merging the irqchip tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

include/linux/irqchip/arm-gic.h:109:53: warning: its scope is only this definition or declaration, which is probably not what you want
In file included from arch/arm/mach-ux500/pm.c:13:0:

                                                     ^

and many more similar.
