Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.collabora.co.uk/git/user/tomeu/linux.git on-demand-probes-v7
commit 4f7c8127d91e752c59ed46f8b894d834740eefac
Author: Tomeu Vizoso <tomeu.vizoso(a)collabora.com>
AuthorDate: Tue Aug 11 10:07:10 2015 +0200

of/platform: Point to struct device from device node
When adding platform and AMBA devices, set the device node's device
member to point to it.
This speeds lookups considerably and is safe because we only create one
of these devices for any given device node.
Signed-off-by: Tomeu Vizoso <tomeu.vizoso(a)collabora.com>
Series-changes: 5
- Set the pointer to struct device also for AMBA devices
- Unset the pointer when the device is about to be unregistered

We can save a line as follows:
if (IS_ENABLED(CONFIG_PREEMPT_COUNT))

This approach also has the advantage of letting the compiler look at
more of the code, so that compiler errors in strange combinations of
configurations are less likely to be missed.
