[PATCH] sched/cpufreq: Fix kobject memleak

From: Tobin C. Harding
Date: Mon Apr 29 2019 - 20:12:42 EST


Currently error return from kobject_init_and_add() is not followed by a
call to kobject_put(). This means there is a memory leak.

Add call to kobject_put() in error path of kobject_init_and_add().
