Subject: jffs2_init_acl_post() can return uninitialized variable

Commit cfc8dc6f6f69ede939e09c2af06a01adee577285 added the following 
function that can return the value of an uninitialized variable:

<--  snip  -->

...
int jffs2_init_acl_post(struct inode *inode)
{
        struct jffs2_inode_info *f = JFFS2_INODE_INFO(inode);
        int rc;

        if (f->i_acl_default) {
                rc = __jffs2_set_acl(inode, JFFS2_XPREFIX_ACL_DEFAULT, f->i_acl_default);
                if (rc)
                        return rc;
        }

        if (f->i_acl_access) {
                rc = __jffs2_set_acl(inode, JFFS2_XPREFIX_ACL_ACCESS, f->i_acl_access);
                if (rc)
                        return rc;
        }

        return rc;
}
