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. Cc: Steven Miao <realmz6@gmail.com> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
