So, as far as I understood it wasn't compiled on 32-bit before, so, it's not a
new error and thus would (has to?) be fixed separately.

I'm not convinced. My assumption is this is triggered because the local pow_10
function was returning int whereas generic int_pow is returning an int64.
Whilst I would imagine it is fairly easy to fix, I'll not have a chance to do
so until the weekend. Perhaps we should just revert this patch and revisit
in the next cycle?
0-day people, any idea why the iio.git/testing branch isn't getting built any
more? I got lazy and started relying on your infrastructure and not bothering
with 32 bit local builds. Somewhere along the way you stopped building it
and I'm afraid I didn't really notice.
Thanks for you all your hard work on 0day btw as it used to catch a lot
of stuff my local few builds didn't!

Hi Jonathan,
Sorry for the inconvenience, we updated the git url to
https://kernel.googlesource.com/pub/scm/linux/kernel/git/jic23/iio.git
recently,
but it seems the branches are not updated, so we switch to use
https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git now.
Best Regards,
Rong Chen

Thanks. I wonder why some trees don't seem to be getting updated in that
google mirror. Anyone know who manages that as a bit silly having
mirrors that are years out of date. Anyone know who manages those mirrors?
I've poked the send feedback form but who knows if it'll filter through to
the right person.
Anyhow, thanks Rong Chen. Looking forwards to continuing to be lazy
and rely on your excellent service!
