Subject: [PATCHv4 00/48] thermal: reorganizing thermal core

Folks,

This is V4 of a patch series to improve thermal core. The idea
here is to reorganize the code and improve the way we
handle sysfs entries.

The change in behavior is that now, thermal zones with empty
.type will not be allowed to be registered. Also, the way
we handle scanf's return code is now checking for
number of successful inputs.

After this series, thermal core is split into the following files:
- thermal_sysfs.c: contains the functions handling the sysfs nodes
- thermal_helpers.c: groups functions that do not need to touch thermal
core internal data structures, such as internal lists, and list locks.
- thermal_core.c: functions to handle the lifecycle of the subsystem,
its governors, cooling devices, thermal zone devices, and their
interactions.

I don't expect any impact on userspace.

Please give your inputs.

For your consideration, I am also adding this to this branch:
  git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal sysfs_rework

V3->V4:
- Fixes on a couple of sysfs entries as reported in the mailing list.

V2->V3:
- Included 8 extra patches to remove style issues on
(new) thermal core.

V1->V2:
- Removed all checkpatch issues in the existing code that was
moved/changed.

Rui, it would be great if you could review these earlier. I will be
sending two extra patch series on top of this one.
