Subject[PATCH] ibmebus/of_platform: Move "name" sysfs attribute into generic OF devices
Date
Recent of_platform changes made of_bus_type_init() overwrite the bus type's
.dev_attrs list, so move ibmebus' "name" attribute (which is needed by eHCA
userspace support) into generic OF device code. Tested on POWER.
