Subject: [PATCH] iommu-api: Add missing header file
Date: Wed, 8 Jun 2011 14:29:11 -0700 [thread overview]
Message-ID: <1307568552-9239-1-git-send-email-lauraa@codeaurora.org> (raw)
If CONFIG_IOMMU_API is not defined some functions will just
return -ENODEV. Add errno.h for the definition of ENODEV.
