[PATCH 2/2] thermal/drivers/thermal_helpers: Adjust output format

[Alexander Stein <alexander.stein@ew.tq-group.com>]

Outputs like this where -1 is printed as unsigned is somewhat misleading
 thermal thermal_zone1: Trip3[type=0,temp=48000]:trend=4,throttle=1
 thermal cooling_device3: cur_state=1
 thermal cooling_device3: old_target=-1, target=2
 thermal cooling_device3: zone1->target=1
 thermal cooling_device3: zone1->target=2
 thermal cooling_device3: zone1->target=18446744073709551615
 thermal cooling_device3: set to state 2

With THERMAL_NO_TARGET assigning -1 as unsigned it make sense to print
the target as signed integer, even if the type is actually unsigned.

An alternative would be to change thermal_instance::target from unsigned
long to long, but this would entail a lot of API & driver changes as well
which looks less intriguing.
