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. [rjw: Fixed up the changelog and changed subject.] Signed-off-by: Stanislaw Gruszka <stf_xl@wp.pl> Cc: stable@kernel.org Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
