Subject: [PATCH] acpiphp: fix missing acpiphp_glue_exit()
Date: Sun, 29 Oct 2006 03:50:48 +0900	[thread overview]
Message-ID: <20061028185048.GI9973@localhost> (raw)

acpiphp_glue_exit() needs to be called to unwind when no slots found.
(It fixes data corruption when reloading acpiphp driver with no such devices)
