[PATCH 2/4] gpio-stmpe: Improve a size determination in stmpe_gpio_probe()

[SF Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 12 Jan 2018 19:36:29 +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.
