Subject: [PATCH 4.9 010/101] selinux: Minor cleanups

From: Andreas Gruenbacher <agruenba@...hat.com>

commit 420591128cb206201dc444c2d42fb6f299b2ecd0 upstream.

Fix the comment for function __inode_security_revalidate, which returns
an integer.

Use the LABEL_* constants consistently for isec->initialized.
