Driver core: Cleanup get_device_parent() in device_add() and device_move()
Make setup_parent() void as get_device_parent() will always return either a valid kobject or NULL. Introduce cleanup_glue_dir() to drop reference grabbed on "glue" directory by get_device_parent(). Use it for cleanup in device_move() and device_add() on errors. This should fix the refcounting problem reported in http://marc.info/?l=linux-kernel&m=120052487909200&w=2 Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Cc: Dave Young <hidave.darkstar@gmail.com> Cc: Gabor Gombas <gombasg@sztaki.hu> Cc: Tejun Heo <htejun@gmail.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Marcel Holtmann <marcel@holtmann.org> Cc: David Miller <davem@davemloft.net> Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
