Subject: checkpatch: Improve parse_email signature checking
Date: Wed, 14 Feb 2018 10:10:05 -0800 [thread overview]
Message-ID: <1518631805.3678.12.camel@perches.com> (raw)
Bare email addresses with non alphanumeric characters require
escape quoting before being substituted in the parse_email routine.
e.g. Reported-by: syzbot+bbd8e9a06452cc48059b@syzkaller.appspotmail.com
Do so.
