The patch titled
swsusp: fix error paths in snapshot_open
has been removed from the -mm tree. Its filename was
swsusp-fix-error-paths-in-snapshot_open.patch
This patch was dropped because it got collaterally broken
------------------------------------------------------
Subject: swsusp: fix error paths in snapshot_open
From: Rafael J. Wysocki <[EMAIL PROTECTED]>
We forget to increase device_available if there's an error in
snapshot_open(), so the snapshot device cannot be open at all after
snapshot_open() has returned an error.
