Subject: [PATCH 09/24]  drivers/iommu: check actual error on iommu_init
Date: Tue, 17 Jun 2014 22:29:19 +0800	[thread overview]
Message-ID: <53A050BF.3000101@oracle.com> (raw)

From: Jie Liu <jeff.liu@oracle.com>

kset_create_and_add() has been fixed to return the actual error
code ptr rather than NULL, so update iommu_init() to check the
return value via IS_ERR() accordingly.
