Subject: [PATCH 3/4] gpio-stmpe: Move an assignment in stmpe_gpio_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 12 Jan 2018 20:44:15 +0100

Move the assignment for the local variable "irq" so that its setting
will only be performed directly before it is checked by this function.
