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.

I've dropped that material from my linux-next branch and Daniel,
please also remove it from your branch that is pulled by linux-next so
that it doesn't show up in there until 6.2-rc1 is out.

It clearly is not ready for merging in its current form.

I rebased a linux-next branch without the generic trip points rework.

It can be inverted with the other changes without conflicts.

I've pushed the branch in case you want to have a look. If you think it is acceptable in this form, I can send a tagged PR for 6.2-rc1 again.

It is still present in my bleeding-edge branch, though, so please
apply the patches from Johan on top of it and send a new PR to me, so
I can add it back to my linux-next branch once 6.2-rc1 appears.

It would be good to check the code again too for any more similar fallout.

I've been through already, the exynos fix is not necessary. But anyway, I agree we should keep these changes for the next release, it is better.
