Subject: [PATCH 4/8] dma-mapping: add a dma_can_mmap helper
Date: Thu, 08 Aug 2019 16:00:01 +0000	[thread overview]
Message-ID: <20190808160005.10325-5-hch@lst.de> (raw)
In-Reply-To: <20190808160005.10325-1-hch@lst.de>

Add a helper to check if DMA allocations for a specific device can be
mapped to userspace using dma_mmap_*.
