    Subject[PATCH 3/3] ste_dma40: Delete an unnecessary variable initialisation in d40_probe()
    From
    Date
    From: Markus Elfring <elfring@users.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.
