Subject: [PATCH 02/44] cpufreq: blackfin: call cpufreq_frequency_table_put_attr()

Drivers which have an exit path must call cpufreq_frequency_table_put_attr() if
they have called cpufreq_frequency_table_get_attr() in their init path.

This driver was missing this part and is fixed with this patch.
