[PATCH 09/24] drivers/iommu: check actual error on iommu_init

From: Jeff Liu
Date: Tue Jun 17 2014 - 10:30:54 EST


From: Jie Liu <jeff.liu@xxxxxxxxxx>

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.
