Subject: [PATCH 2/8] dma-mapping: move the dma_get_sgtable API comments from arm to common code
Date: Thu, 08 Aug 2019 15:59:59 +0000	[thread overview]
Message-ID: <20190808160005.10325-3-hch@lst.de> (raw)
In-Reply-To: <20190808160005.10325-1-hch@lst.de>

The comments are spot on and should be near the central API, not just
near a single implementation.
