From: Rob Herring Date: Wed, 30 Oct 2013 04:36:46 +0000 (-0500) Subject: of: set dma_mask to point to coherent_dma_mask X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0589342c27944e50ebd7a54f5215002b6598b748;p=openwrt%2Fstaging%2Fblogic.git of: set dma_mask to point to coherent_dma_mask Platform devices created by DT code don't initialize dma_mask pointer to anything. Set it to coherent_dma_mask by default if the architecture code has not set it.
