Compile testing
---------------
We compiled the kernel for 4 architectures:
aarch64:
make options: make -j30 INSTALL_MOD_STRIP=1 targz-pkg
ppc64le:
make options: make -j30 INSTALL_MOD_STRIP=1 targz-pkg
s390x:
make options: make -j30 INSTALL_MOD_STRIP=1 targz-pkg
x86_64:
make options: make -j30 INSTALL_MOD_STRIP=1 targz-pkg

Aborted tests
-------------
Tests that didn't complete running successfully are marked with ⚡⚡⚡.
If this was caused by an infrastructure issue, we try to mark that
explicitly in the report.
Waived tests
------------
If the test run included waived tests, they are marked with 🚧. Such tests are
executed but their results are not taken into account. Tests are waived when
their results are not reliable enough, e.g. when they're just introduced or are
being fixed.
Testing timeout
---------------
We aim to provide a report within reasonable timeframe. Tests that haven't
finished running yet are marked with ⏱.
This is a note to let you know that I've just added the patch titled
iio: adc: gyroadc: fix leak of device node iterator
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-testing branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will be merged to the staging-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Subject: iio: adc: gyroadc: fix leak of device node iterator
Add missing of_node_put calls when exiting the for_each_child_of_node
loop in rcar_gyroadc_parse_subdevs early.
Also add goto-exception handling for the error paths in that loop.

Subject: iio: adc: at91-sama5d2_adc: fix DMA conversion crash
After the move of the postenable code to preenable, the DMA start was
done before the DMA init, which is not correct.
The DMA is initialized in set_watermark. Because of this, we need to call
the DMA start functions in set_watermark, after the DMA init, instead of
preenable hook, when the DMA is not properly setup yet.
