From 6659ca2ab6730c3bbb9fa495f2327b95b955decd Mon Sep 17 00:00:00 2001 From: Kylene Hall Date: Thu, 23 Jun 2005 22:02:00 -0700 Subject: [PATCH] tpm: sysfs owernship changes In the current driver all sysfs files end up owned by the base driver module rather than the module that actually owns the device this is a problem if the module is unloaded and the file is open. This patch fixes all that and lumps the files into an attribute_group.
