For every other sensor the human readable name of cpu0 is "CPU 1" and so
on, except clock speed
Before (in ksysguardd -i)
ksysguardd> cpu/cpu0/sys?
CPU 1 System Load 0 100 %
ksysguardd> cpu/cpu0/clock?
CPU0 Clock Frequency 0 0 MHz
With this patch they're uniform
Doesn't make a big difference as SensorManager goes through a big
translation and disregards this anyway.
