From 22d9d8e8316d7f69046c8805ce9aa8d9c43d4e5b Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 10 Jun 2013 16:28:49 +0100 Subject: DMA-API: usb: 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.
