Subject: [PATCH 3/3] ste_dma40: Delete an unnecessary variable initialisation
 in d40_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 16 Nov 2015 22:00:28 +0100

The variable "res" will eventually be set to a resource pointer from
a call of the d40_hw_detect_init(() function.
Thus let us omit the explicit initialisation at the beginning.
