Subject: [PATCH 2/2] Input: gtco: Improve a size determination in gtco_probe()
Date: Wed, 24 Jan 2018 16:15:59 +0100	[thread overview]
Message-ID: <0c363cc1-5532-e482-82bf-c8b59c2bd72f@users.sourceforge.net> (raw)
In-Reply-To: <5c4410ab-5174-ce8d-cab6-7979aa61f996@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 24 Jan 2018 15:08:42 +0100

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.
