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