[PATCH 00/35] cpufreq: Introduce cpufreq_table_validate_and_show()

[Viresh Kumar]

This is actually part of a bigger patchset which will change declaration of
cpufreq_driver->target() to include index instead of target_freq and relation
and hence cpufreq drivers wouldn't require to cpufreq_frequency_table_target()
anymore.

Almost every cpufreq driver is required to validate its frequency table with:
cpufreq_frequency_table_cpuinfo() and then expose it to cpufreq core with:
cpufreq_frequency_table_get_attr().

This patch creates another helper routine cpufreq_table_validate_and_show() that
will do both these steps in a single call and will return 0 for success, error
otherwise.

This also fixes potential bugs in cpufreq drivers where people have called
cpufreq_frequency_table_get_attr() before calling
cpufreq_frequency_table_cpuinfo(), as the later may fail.
