From 0a5549ed163520787f76b7515dfe9d9aa1c7ae37 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 23 Jun 2009 22:52:51 +0200 Subject: lib/checksum: fix one more thinko When do_csum gets unaligned data, we really need to treat the first byte as an even byte, not an odd byte, because we swap the two halves later. Found by Mike's checksum-selftest module.
