Subject: [PATCH v3 05/34] iommu/amd: Remove dma_mask check from check_device()
Date: Wed, 29 Apr 2020 15:36:43 +0200	[thread overview]
Message-ID: <20200429133712.31431-6-joro@8bytes.org> (raw)
In-Reply-To: <20200429133712.31431-1-joro-zLv9SwRftAIdnm+yROfE0A@public.gmane.org>

From: Joerg Roedel <jroedel-l3A5Bk7waGM@public.gmane.org>

The check was only needed for the DMA-API implementation in the AMD
IOMMU driver, which no longer exists.

Signed-off-by: Joerg Roedel <jroedel-l3A5Bk7waGM@public.gmane.org>
