From d5dae721308ac5d5db03bf3aebaa15fcdcfb4862 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 6 May 2013 15:02:40 +1000 Subject: [PATCH] powerpc/topology: Fix spurr attribute permission We are registering the attribute with permission 0600 but it doesn't have a store callback, which causes WARN_ON's during boot. Fix the permission.
