    cpufreq: Add new helper cpufreq_table_validate_and_show() · 27047a60
    Viresh Kumar authored
    Almost every cpufreq driver is required to validate its frequency table with:
    cpufreq_frequency_table_cpuinfo() and then expose it to cpufreq core with:
    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
    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.
