[PATCH 3.19 138/177] sd: Unregister integrity profile

[Greg Kroah-Hartman]

3.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Martin K. Petersen" <martin.petersen@xxxxxxxxxx>

commit e727c42bd55794765c460b7ac2b6cc969f2a9698 upstream.

The new integrity code did not correctly unregister the profile for SD
disks. Call blk_integrity_unregister() when we release a disk.
