    usb: dwc3: gadget: Properly initialize LINK TRB · 1200a82a
    Jack Pham authored
    On ISOC endpoints the last trb_pool entry used as a
    LINK TRB is not getting zeroed out correctly due to
    memset being called incorrectly and in the wrong place.
    If pool allocated from DMA was not zero-initialized
    to begin with this will result in the size and ctrl
    values being random garbage. Call memset correctly after
    assignment of the trb_link pointer.
