Subject: [PATCH 2/3] serial: ifx6x60: Improve a size determination in ifx_spi_spi_probe()
Date: Sat, 9 Dec 2017 20:12:21 +0100	[thread overview]
Message-ID: <2134a9fd-73d9-686f-cc41-0d143a62cbbe@users.sourceforge.net> (raw)
In-Reply-To: <992f55e5-961d-79ea-a6cd-441ceb3ad058@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 9 Dec 2017 19:22:50 +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.
