From 4589f1fe570c2c786b72eff146b2f168821882c6 Mon Sep 17 00:00:00 2001 From: Joachim Fenkes Date: Wed, 6 Aug 2008 00:30:18 +1000 Subject: powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devices Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.
