From bda2b180545b2ef586658ed5c3312cb947a2a6c9 Mon Sep 17 00:00:00 2001 From: Pratyush Anand Date: Fri, 18 Jan 2013 16:53:56 +0530 Subject: [PATCH] usb: dwc3: gadget: fix ep->maxburst for ep0 commit 6048e4c69d80600baba35856651056860d5d8f5a upstream. dwc3_gadget_set_ep_config expects maxburst as incremented by 1. So, by default initialize ep->maxburst to 1 for ep0.
