From 7a341066117f9eb5eb9385f61176ef6a08b90163 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Fri, 28 Oct 2011 07:37:04 +0200 Subject: [PATCH] e1000: fix bugs from recent commits Commit 114d7fc0 "e1000: Rewrite EEPROM checksum error to give more information" failed to initialize the checksum variable which should result in random results. Fix that. Commit 2326a94d caused a ton of "unused variable 'x'" warnings. Fix these. While we are at it, remove some bogus parens.
