[PATCH 2/2] cpufreq: drivers: Remove unnecessary assignments of policy-> members

[Viresh Kumar]

Some assignments of policy-> min/max/cur/cpuinfo.min_freq/cpuinfo.max_freq
aren't required as part of it is done by cpufreq driver or cpufreq core.

Remove them.

At some places we merge multiple lines together too.

There is a line in the code a little above the ones you deleted that
also sets these same variables. I guess you were relying on that line to
set policy->cur, but that also sets policy->{min, max} which can be
cleaned up.

This code is rather confusing or wrong, this was the state of code before
this patch:

	policy->cur = policy->min = policy->max = davinci_getspeed(0);

	if (freq_table) {
		result = cpufreq_frequency_table_cpuinfo(policy, freq_table);
		if (!result)
			cpufreq_frequency_table_get_attr(freq_table,
							policy->cpu);
	} else {
		policy->cpuinfo.min_freq = policy->min;
		policy->cpuinfo.max_freq = policy->max;
	}

        policy->min = policy->cpuinfo.min_freq;
        policy->max = policy->cpuinfo.max_freq;
        policy->cur = davinci_getspeed(0);


The tricky part is if/else, where if don't return error if
cpufreq_frequency_table_cpuinfo() fails. We want to set ->min[max]
and cpuinfo.min[max] always. And i can see this code not doing that for some
case even with my patch.

Possible scenarios:
1. Valid freq_table: My patch + what you suggested is required.
2. Invalid freq_table: We never set cpuinfo.min[max] with or without my patch
3. No freq_table: Only my patch is required.

If i do what you suggested then 2 and 3 would fail... If you want to
return error
in case cpufreq_frequency_table_cpuinfo(), then i can fix it properly.

So down in the cpufreq driver probe below, we bail out if freq_table is
not provided. So all this checking for freq_table in the code you pasted
above is superfluous. If you can clean that part up and add checking for
cpufreq_frequency_table_cpuinfo() as you proposed, I will be glad to
test it out ;)

Thanks,
Sekhar
