    Subject[PATCH 9/9] staging: ks7010: Delete three unnecessary variable initialisations
    From
    Date
    From: Markus Elfring <elfring@users.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.
