linux-next: build failure after merge of the gpio-lw tree
July 06, 2012 08:20AM
Hi Linus,

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

ERROR: "irq_set_chip_and_handler_name" [drivers/gpio/gpio-pcf857x.ko] undefined!
ERROR: "dummy_irq_chip" [drivers/gpio/gpio-pcf857x.ko] undefined!

I have dropped the gpio-lw tree for today.

Thanks, I've dropped the offending patch, Kuninori can you look into this and
provide a new patch? It's the second patch from your patch set.

OK. I will, but it will be next week.
And could you please show me where is your repository/branch ?

In my check, these are export symbol issue.
I think above 2 function/struct were not exported for module.

Is it poosible to solve this issue by these patches ?

Hm Thomas has to answer to that (and merge the patches, if he
likes them).

get_maintainer.pl showed me that Thomas is the maintainer
of ${LINUX}/kernel/irq/,
but am I wrong ?
I think there is no response for these patches.

Who can care these patches ?
Should I resend again ?
