From 8a7aef2cb3dafd2e8560750f4e5ad2cc2d9b1d17 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 29 Oct 2016 21:37:02 +0200 Subject: [PATCH] powerpc/iommu: Use permission-specific DEVICE_ATTR variants Use DEVICE_ATTR_RW for read-write attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies.
