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 was merged into mainline or a subsystem tree ------------------------------------------------------ Subject: swsusp: fix error paths in snapshot_open From: Rafael J. Wysocki <rjw@xxxxxxx> 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.
