    Subject[PATCH 4/7] USB-iowarrior: Delete unnecessary initialisations in iowarrior_open()
    From
    Date
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Sun, 21 Aug 2016 15:15:03 +0200

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