Hi,
I see 6 out of 24 arm qemu tests failing in next-20160111. Bisect points
to commit 989561de9b51 ("PM / Domains: add setter for dev.pm_domain").
Failures are silent - there is no output on the console.
Affected tests are
arm:beagle:multi_v7_defconfig:omap3-beagle
arm:beaglexm:multi_v7_defconfig:omap3-beagle-xm
arm:overo:multi_v7_defconfig:omap3-overo-tobi
arm:beagle:omap2plus_defconfig:omap3-beagle
arm:beaglexm:omap2plus_defconfig:omap3-beagle-xm
arm:overo:omap2plus_defconfig:omap3-overo-tobi
For details please see the 'next' column at http://server.roeck-us.net:8010/builders.

Please let me know if there is anything I can do to help tracking down the problem.

proper fix?

If I'm not mistaken, what happens is that device_is_bound() tries to
dereference dev->p which is NULL. If that's the case, the appended one
should help too.
Can you please check?

Yes, that fixes the problem as well.
