Hello Angelo,

The commit message is not clear.
The clients are cpufreq and mediatek cci.
I think there is no any error before introducing mediatek cci into
cpufreq.

The order of this patch should be after "cpufreq: mediatek: Link CCI
device to CPU".

If so, I will also correct the commit message in next version.

BRs,
Rex
