Subject: [PATCH 2/7] VMCI: Improve a size determination in two functions
Date: Wed, 10 Jan 2018 20:25:53 +0100	[thread overview]
Message-ID: <05412529-d0e2-0894-6229-431caa48c498@users.sourceforge.net> (raw)
In-Reply-To: <2747f123-a95d-bc68-b858-0327dce3758b@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 10 Jan 2018 17:47:40 +0100

Replace the specification of data structures by pointer dereferences
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.
