Subject: [PATCH 14/47] PM: PCI and IDE handle PM_EVENT_PRETHAW
Date: Mon, 25 Sep 2006 22:37:34 -0700 [thread overview]
Message-ID: <11592491274168-git-send-email-greg@kroah.com> (raw)
In-Reply-To: <1159249124371-git-send-email-greg@kroah.com>
From: David Brownell <david-b@pacbell.net>
Convert some framework code to handle the new PRETHAW message.
- IDE just treats it like a FREEZE.
- The pci_choose_state() thingie still doesn't use PCI_D0 when it gets a
FREEZE (and now PRETHAW) event, which seems rather buglike but wasn't
something to change with this patch.
