That statement was true when we didn't had this problem..

This doesn't look right. It can happen to some other drivers as well in future.
So, there are two solutions I can think of:
1. move cpufreq_next_valid and rename it to __cpufreq_next_valid(). Also make it
inline. Then create two versions of cpufreq_next_valid(), one inlined (only when
CONFIG_CPU_FREQ=n) and other one in cpufreq.c (non- inlined)..

But probably that would be called ugly by some people :)

2. Make cpufreq_next_valid() inline and forget about extra space it takes :)

@Rafel: Let me know which one you like :)
