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. Signed-off-by: Tejun Heo <htejun@xxxxxxxxx> --- Pavel, I took your advice and chose to disable unconditionally rather than recording the status separately, but I still think it would be nice if we can tell the status we're waking from from either the mesg itself (say, PM_EVENT_THAW) or recorded prev state. Both STM and STD are tested. Please apply. Thanks.
