Subject: iommu-api: Add missing header file
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=74315cccd2104a953f493acca2c6b0519d6f5c6f;p=openwrt%2Fstaging%2Fblogic.git

iommu-api: Add missing header file

If CONFIG_IOMMU_API is not defined some functions will just
return -ENODEV. Add errno.h for the definition of ENODEV.
