Relax the thermal governor requirements of sustainable_power and at
least two trip points so that it can be bound to any thermal zone.
Its behavior won't be optimal, it would be the best possible with the
data provided.
Changes since v4:
- Fix crash when a thermal zone with no trip points has
Thermal zones created using thermal_zone_device_create() may not have
tzp. As the governor gets its parameters from there, allocate it while
the governor is bound to the thermal zone so that it can operate in it.
In this case, tzp is freed when the thermal zone switches to another
governor.
Cc:
The power allocator governor currently requires that the thermal zone
has at least two passive trip points. If there aren't, the governor
refuses to bind to the thermal zone.
This commit relaxes that requirement. Now the governor will bind to all
thermal zones regardless of how many trip points
The thermal core already has a function to get the maximum power of a
cooling device: power_actor_get_max_power(). Add a function to get the
minimum power of a cooling device.

This commit doesn't change any functionality, but should provide better

Rename scale() to cap_scale() to better reflect
The power allocator governor currently requires that a sustainable power
is passed as part of the thermal zone's thermal zone parameters. If
that parameter is not provided, it doesn't register with the thermal
zone.
While this parameter is strongly recommended for optimal performance, it
doesn't

The data race happens on ps2dev->cmdcnt and ps2dev->cmdbuf contents.
__ps2_command reads that data concurrently with the interrupt handler.

The validation checks that the values that were just assigned, got
assigned i.e. the error can't ever happen. Subsequent patches will
call this code in places where errors are not being returned.
Changing those code paths to return this non-existent error is
counter-productive, so just remove it.
perf_evlist__propagate_maps() incorrectly assumes evsel->threads
is NULL before reassigning it, but it won't be NULL when
perf_evlist__set_maps() is used to set different (or NULL) maps.
Thus thread_map__put must be used, which works even if
evsel->threads is NULL.

I executed a clone detection tool* on drivers source code and I found
that there are similar files between drivers/gpu/drm/amd/ and
drivers/gpu/drm/radeon, but also inside each of theses folders.
Some examples:
drivers/gpu/drm/amd/amdgpu/dce_v11_0.c,drivers/gpu/drm/amd/amdgpu/dce_v10_0.c
