Subject: [PATCH] XFS: Use a signed return type for suffix_kstrtoint()
Date: Sun, 20 Dec 2015 08:00:29 +0100 [thread overview]
Message-ID: <5676520D.2060806@users.sourceforge.net> (raw)
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 20 Dec 2015 07:56:36 +0100
The return type "unsigned long" was used by the suffix_kstrtoint()
function even though it will eventually return a negative error code.
Improve this implementation detail by using the type "int" instead.
This issue was detected by using the Coccinelle software.
