[PATCH] gpio-ucb1400: Delete an unnecessary variable initialisation in ucb1400_gpio_probe()

[SF Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 25 Dec 2015 19:36:20 +0100

The variable "err" will eventually be set to an appropriate value
from a call of the gpiochip_add() function.
Thus let us omit the explicit initialisation at the beginning.
