[-- Attachment #1: Type: text/plain, Size: 706 bytes --] Hi Linus, After merging the gpio tree, today's linux-next build (powerpc allyesconfig) produced these warnings: drivers/gpio/gpio-ucb1400.c: In function 'ucb1400_gpio_remove': drivers/gpio/gpio-ucb1400.c:92:2: warning: ignoring return value of 'gpiochip_remove', declared with attribute warn_unused_result [-Wunused-result] gpiochip_remove(&ucb->gc); ^ And lots of similar ones. Introduced by commit 9f5132ae82fd ("gpio: remove all usage of gpio_remove retval in driver/gpio"). Maybe the __must_check attribute should be removed from the declaration of the function before removing the retval checking ... -- Cheers, Stephen Rothwell sfr@canb.auug.org.au [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 819 bytes --]

Hey, good idea. I'll do this. Yours, Linus Walleij

I have absolutely no clue either.
What I know is that there is a device tree compiler warning that can
be turned on, and
it generates these warnings a lot. The actual problems have been in
the DTS files
forever. They just recently started to look into them.
It has nothing to do with the GPIO tree whatsoever, so I wonder if it
is a side effect of
something else?
Yours,
Linus Walleij

There's a dtc update in -next which adds these new checks. It's been
there for over a month now. Unlike other dtc checks, these are
generally actual errors, so they are not off by default (enabled with
W=1,2).
In reality, there's only about 50-100 warnings. The way dts includes
are structured and because the dtc checks don't have the original
source file lines, it just multiplies the warnings.

arm multi_v7_defconfig builds of Linus' tree :-(

Well, there's these five in -next that I guess haven't been sent to Linus yet:
912d7985f3ce ARM: dts: rockchip: fix rk3288 iep-IOMMU interrupts property cells
44e5dced2ef6 arm: dts: marvell: Add missing #phy-cells to usb-nop-xceiv
d53418dfe997 ARM: dts: imx: Add missing #phy-cells to usb-nop-xceiv
f0e11ff8ff65 ARM: dts: am33xx: Add missing #phy-cells to ti,am335x-usb-phy
f568f6f554b8 ARM: dts: omap: Add missing #phy-cells to usb-nop-xceiv
These 2 aren't in -next and seem to have been missed:
arm: dts: qcom: fix missing #phy-cells for apq8064
arm: dts: nspire: Add missing #phy-cells to usb-nop-xceiv
Arnd, Olof, can you pick these up?
