From d6cfaaba1a93a239b01bc8d1351685773b657b64 Mon Sep 17 00:00:00 2001 From: Russell King <rmk+kernel@arm.linux.org.uk> Date: Mon, 10 Jun 2013 18:41:59 +0100 Subject: DMA-API: others: use dma_set_coherent_mask() The correct way for a driver to specify the coherent DMA mask is not to directly access the field in the struct device, but to use dma_set_coherent_mask(). Only arch and bus code should access this member directly. Convert all direct write accesses to using the correct API.
