Tobin C. Harding 290da8e79c sched/cpufreq: Fix kobject memleak
[ Upstream commit 9a4f26cc98 ]

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().
