Subject: [PATCH 4.16 29/72] dm integrity: use kvfree for kvmallocd memory

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

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

From: Mikulas Patocka <mpatocka@...hat.com>

commit fc8cec113904a47396bf0a1afc62920d66319d36 upstream.

Use kvfree instead of kfree because the array is allocated with kvmalloc.

Fixes: 7eada909bfd7a ("dm: add integrity target")
