Subject: [PATCH 4/4] gpio-stmpe: Delete an unnecessary variable initialisation
 in stmpe_gpio_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 12 Jan 2018 20:48:40 +0100

The local variable "irq" will eventually be set to an appropriate value
a bit later. Thus omit the explicit initialisation at the beginning.
