Commit Message

  From: Roberto Sassu <roberto.sassu@huawei.com>

With the recent introduction of LSM_ORDER_LAST, the 'integrity' LSM is
always initialized (if selected in the kernel configuration) and the
iint_cache is always created (the kernel panics on error). Thus, the
additional check of iint_cache in integrity_inode_get() is no longer
necessary. If the 'integrity' LSM is not selected in the kernel
configuration, integrity_inode_get() just returns NULL.

This reverts commit 92063f3ca73aab794bd5408d3361fd5b5ea33079.
