From 881c6cfd7c5edfe6129006e2404654bfe5911050 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 1 Nov 2007 09:29:06 -0600 Subject: [PATCH] kset: convert /sys/devices to use kset_create Dynamically create the kset instead of declaring it statically. We also rename devices_subsys to devices_kset to catch all users of the variable.
