From 4c90d9717ae27dddf4b02ed7d683e502b539cd1c Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 20 Feb 2007 18:14:48 +0900 Subject: [PATCH 1/1] libata: disable pdev on all suspend events libata used disable pdev only on PM_EVENT_SUSPEND while re-enable pdev unconditionally. This was okay before ref-counted pdev enable update but it now makes the pdev pinned after swsusp cycle (enabled twice but disabled only once) and devres sanity check whines about it. Fix it by unconditionally disabling pdev on all suspend events.
