Subject: [RFC v2 0/9] Stop monitoring disabled devices

This is the second iteration of this RFC.

The series now focuses on cleaning up the code in the first place.

After the cleanups in patches 1-3 struct thermal_zone_device is extended
so that it contains a "mode" member (patch 4/9).

The next patch (5/9) makes all thermal zone devices use the "mode" member.
This patch makes drivers' ->get_mode() methods redundant, so the next one
(6/9) removes the method altogether.

Patches 7-8/9 ensure that after changing thermal zone device's mode
an attempt will be made to monitor the device.

And finally patch 9/9 prevents DISABLED devices from being monitored.
It also adds THERMAL_DEVICE_INITIAL to accommodate the devices, which
should be monitored but cannot be initially ENABLED.

Andrzej Pietrasiewicz (9):
  thermal: int3400_thermal: Statically initialize
    .get_mode()/.set_mode() ops
  thermal: Eliminate an always-false condition
  thermal: Properly handle mode values in .set_mode()
  thermal: core: Let thermal zone device's mode be stored in its struct
  thermal: Store mode in thermal_zone_device
  thermal: Remove get_mode() method
  thermal: core: Monitor thermal zone after mode change
  thermal: of: Monitor thermal zone after enabling it
  thermal: core: Stop polling DISABLED thermal devices
