Subject: [PATCH] scripts: coccinelle: boolinit: drop warnings on named constants
Date: Sat, 29 Dec 2018 07:14:16 +0100	[thread overview]
Message-ID: <1546064056-15569-1-git-send-email-Julia.Lawall@lip6.fr> (raw)

Coccinelle doesn't always have access to the values of named
(#define) constants, and they may likely often be bound to true
and false values anyway, resulting in false positives.  So stop
warning about them.
