From 386f275f5d097758f867bc99ddeaeb7a03b6b190 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Fri, 2 Nov 2007 13:47:53 +0100 Subject: Driver Core: switch all dynamic ksets to kobj_sysfs_ops Switch all dynamically created ksets, that export simple attributes, to kobj_attribute from subsys_attribute. Struct subsys_attribute will be removed.
