Subject: [PATCH 9/9] staging: ks7010: Delete three unnecessary variable
 initialisations

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 17 Jul 2016 19:40:47 +0200

Three variables will be set to an appropriate value a bit later.
Thus omit the explicit initialisation at the beginning.
