Subject: [PATCH 13/14] cpufreq: cpu0: rename driver and internals to 'cpufreq_generic'
This is not a cpu0 driver anymore as it supports any number of clusters with
separate clock/voltage lines.
Lets rename it to 'cpufreq_generic' from 'cpufreq_cpu0'.
'.name' field of platform driver/devices isn't renamed yet, would be done
separately.
