Subject: [RHEL5 PATCH 2/5] pciehp: info messages are confusing
Date: Wed, 29 Nov 2006 12:41:02 -0500
Bugzilla: 216932
Message-Id: <456DC62E.7060104@redhat.com>
Changelog: pciehp: info messages are confusing


BZ216932
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=216932

This fix is in upstream.

The slot number displayed in info messages would cause confusion
because those are displayed in several ways (decimal and hex).
Furthermore, those slot number is not same as slot name (directory
name).  This patch fixes those improper info messages.

This patch applies to -2.6.18-1.2747.el5 and I have verified
that it worked all right.

Thanks,
Kei
