[PATCH 44/46] mod_sysfs_setup() doesn't return errno when kobject_add_dir() failure occurs

[Greg Kroah-Hartman]

From: Akinobu Mita <akinobu.mita@xxxxxxxxx>

mod_sysfs_setup() doesn't return an errno when kobject_add_dir() for module
"holders" directory fails.  So caller of mod_sysfs_setup() will keep going
and get oops.
