From eb3a58de3ec4940fc6b2a9f810895d772a2a9794 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 8 May 2017 15:55:42 -0700 Subject: [PATCH] checkpatch: allow space leading blank lines in email headers Allow a leading space and otherwise blank link in the email headers as it can be a line wrapped Spamassassin multiple line string or any other valid rfc 2822/5322 email header. The line with space causes checkpatch to erroneously think that it's in the content body, as opposed to headers and thus flag a mail header as an unwrapped long comment line.
