[PATCH 01/23] iommu/dma: Cleanup dma-iommu.h
From: Christoph Hellwig
Date: Thu May 23 2019 - 03:03:27 EST
No need for a __KERNEL__ guard outside uapi and add a missing comment
describing the #else cpp statement. Last but not least include
<linux/errno.h> instead of the asm version, which is frowned upon.
