commit: 2e725a065b0153f0c449318da1923a120477633d From: Stanislaw Gruszka <[email protected]> Date: Sat, 12 Feb 2011 21:06:51 +0100 Subject: [PATCH] PM / Hibernate: Return error code when alloc_image_page() fails
Currently we return 0 in swsusp_alloc() when alloc_image_page() fails. Fix that. Also remove unneeded "error" variable since the only useful value of error is -ENOMEM.
