    Subject[PATCH 19/93] usb: dwc3: gadget: fix ep->maxburst for ep0
    Date
    3.5.7.5 -stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Pratyush Anand <pratyush.anand@st.com>

    commit 6048e4c69d80600baba35856651056860d5d8f5a upstream.

    dwc3_gadget_set_ep_config expects maxburst as incremented by 1. So, by
    default initialize ep->maxburst to 1 for ep0.
