From 3a14c66d43d018baed96ceb74f9ab548878c09b8 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 27 Apr 2016 14:15:40 +0300 Subject: dmaengine: dw: pass platform data via struct dw_dma_chip We pass struct dw_dma_chip to dw_dma_probe() anyway, thus we may use it to pass a platform data as well. While here, constify the source of the platform data.
