Subject: [PATCH 4.19 29/91] drm/vmwgfx: fix a warning due to missing dma_parms
Date: Fri, 12 Jul 2019 14:18:32 +0200 [thread overview]
Message-ID: <20190712121622.951304016@linuxfoundation.org> (raw)
In-Reply-To: <20190712121621.422224300@linuxfoundation.org>
[ Upstream commit 39916897cd815a0ee07ba1f6820cf88a63e459fc ]
Booting up with DMA_API_DEBUG_SG=y generates a warning due to the driver
forgot to set dma_parms appropriately. Set it just after vmw_dma_masks()
in vmw_driver_load().
DMA-API: vmwgfx 0000:00:0f.0: mapping sg segment longer than device
claims to support [len=2097152] [max=65536]
