Subject[PATCH 2/3] parport: ax88796: Improve a size determination in parport_ax88796_probe()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 29 Dec 2017 17:03:30 +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.
