From ba0fc709e197415aadd46b9ec208dc4abaa21edd Mon Sep 17 00:00:00 2001 From: Vitaly Bordug <vitb@kernel.crashing.org> Date: Wed, 9 Jul 2008 13:13:38 +1000 Subject: [PATCH] powerpc: Add missing reference to coherent_dma_mask There is dma_mask in of_device upon of_platform_device_create() but we don't actually set coherent_dma_mask. This may cause weird behavior of USB subsystem using of_device USB host drivers.
