From 4552a0ca61cb2133bc77dc432ea20538ea28638a Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 24 May 2012 09:19:31 +0300 Subject: [PATCH] usb: dwc3: fix a WARN and a comment we're now have DWC3_EP0_BOUNCE_SIZE to tell us the actual size of the bufer. Let's use that instead of ep0 wMaxPacketSize.
