From 334c6307543a2b8af730a422f466d5f9442b606a Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 2 Nov 2007 13:20:40 -0700 Subject: [PATCH] kobject: convert efivars to kobj_attr interface This cleans up a lot of code and gets rid of a unneeded macro, and gets us one step closer to deleting the deprecated subsys_attr code.
