commit 3f5b9959041e0db6dacbea80bb833bff5900999f upstream.
When CONFIG_DEVFREQ_THERMAL is disabled all functions except
of_devfreq_cooling_register_power() were already inlined. Also inline
the last function to avoid compile errors when multiple drivers call
of_devfreq_cooling_register_power() when CONFIG_DEVFREQ_THERMAL is not
set. Compilation failed with the following message:
multiple definition of `of_devfreq_cooling_register_power'
(which then lists all usages of of_devfreq_cooling_register_power())
Thomas Zimmermann reported this problem [0] on a kernel config with
CONFIG_DRM_LIMA={m,y}, CONFIG_DRM_PANFROST={m,y} and
CONFIG_DEVFREQ_THERMAL=n after both, the lima and panfrost drivers
gained devfreq cooling support.

thermal: devfreq_cooling: use a thermal_cooling_device for register and unregister2015-11-02T21:14:44ZJavi Merinojavi.merino@arm.com2015-11-02T19:03:03Zurn:sha1:3c99c2cef75eb5bfc05c5728e4560f3ee656d47e
Be consistent with what other cooling devices do and return a struct
thermal_cooling_device * on register. Also, for the unregister, accept
a struct thermal_cooling_device * as parameter.

thermal: Add devfreq cooling2015-10-30T17:21:01ZØrjan Eideorjan.eide@arm.com2015-09-10T17:09:30Zurn:sha1:a76caf55e5b356ba20a5a43ac4d9f7a04b20941d
Add a generic thermal cooling device for devfreq, that is similar to
cpu_cooling.
The device must use devfreq. In order to use the power extension of the
cooling device, it must have registered its OPPs using the OPP library.
