Subject: [PATCH 09/24] ste_dma40: Delete unnecessary variable initialisations
 in d40_hw_detect_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 17 Sep 2016 14:34:18 +0200

Five local variables will be set to an appropriate value a bit later.
Thus omit the explicit initialisation which became unnecessary with
a previous update step.
