From: Viresh Kumar <viresh.ku...@linaro.org> [ Upstream commit 9a4f26cc98d81b67ecc23b890c28e2df324e29f3 ]
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: Tobin C.
