Subject[PATCH 0/4] thermal: fix locking regressions in linux-next
This series fixes some of the fallout after the thermal changes that
just landed in linux-next.

Lockdep reported a lock inversion in one of the Qualcomm drivers and a
closer review revealed that the changes had also broken the sysfs
interface for at least three drivers.

Note that a simple revert of the offending patches was not an option as
some of the infrastructure that the old implementation relied on has
also been removed.


Johan Hovold (4):
thermal/drivers/qcom: fix set_trip_temp() deadlock
thermal/drivers/exynos: fix set_trip_temp() deadlock
