From 270c49a088ae58d4b817861bb04bfec63b0966db Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 10 Jan 2012 15:09:50 -0800 Subject: [PATCH] checkpatch: update signature "might be better as" warning email header lines can look like signature tags. It's valid to have multiple email recipients on a single line but not valid to have multiple signatures on a single line. Validate signatures only when not in the email headers. Clear the $in_commit_log flag when the patch filename appears. Add '-' to the valid chars in a message header for headers like "Message-Id:" and "In-Reply-To:".
