cpufreq: Fix kobject memleak
Currently the error return path from kobject_init_and_add() is not followed by a call to kobject_put() - which means we are leaking the kobject. Fix it by adding a call to kobject_put() in the error path of kobject_init_and_add(). Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Reviewed-by: Tobin C. Harding <tobin@kernel.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
