Subject[PATCH] edac: Fix reference count leak in edac_device_register_sysfs_main_kobj.
Date
From: Qiushi Wu <wu000273@umn.edu>

kobject_init_and_add() should be handled when it return an error,
because kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object. Previous
commit "b8eb718348b8" fixed a similar problem.

Fixes: b2ed215a3338 ("Kobject: change drivers/edac to use kobject_init_and_add")
Signed-off-by: Qiushi Wu <wu000273@umn.edu>
