Subject: [cip-dev] [PATCH 4.19.y 25/60] dmaengine: rcar-dmac: set scatter/gather max segment size
Date: Wed, 28 Aug 2019 12:02:56 +0100 [thread overview]
Message-ID: <1566990211-24785-26-git-send-email-fabrizio.castro@bp.renesas.com> (raw)
In-Reply-To: <1566990211-24785-1-git-send-email-fabrizio.castro@bp.renesas.com>
From: Wolfram Sang <wsa+renesas@sang-engineering.com>
commit 97d49c59e219acac576e16293a6b8cb99302f62f upstream.
Fix warning when running with CONFIG_DMA_API_DEBUG_SG=y by allocating a
device_dma_parameters structure and filling in the max segment size.
