Subject: [PATCH] block: remove unnecessary NULL checks in
Git-commit: 4b14a5c5d57f4fd6929db3427ba4d7c3775b4680
Patch-mainline: v4.15-rc1
References: bsc#1104967,FATE#325924
bioset_integrity_free()
mempool_destroy() already checks for a NULL value being passed in, this
eliminates duplicate checks.
This was caught by running make coccicheck M=block/ on linus' tree on
commit 77ede3a014a32746002f7889211f0cecf4803163 (current head as of this
patch).
