From 7b6c0f8034d78390f9185e2ec2edb0a3e4ad244e Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 9 Dec 2015 13:21:23 +0300 Subject: [PATCH] blk-integrity: checking for NULL instead of IS_ERR We recently changed bio_integrity_alloc() to return ERR_PTRs instead of NULL but these calls were missed.
