From 6f7850bb86a521f6da68794548a34dfa7ea7e1b9 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Sat, 12 Feb 2011 21:06:51 +0100 Subject: [PATCH] PM / Hibernate: Return error code when alloc_image_page() fails commit 2e725a065b0153f0c449318da1923a120477633d upstream. 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.
