From 70b674bfeb735557fc03cdc125ffe6d34218fcfd Mon Sep 17 00:00:00 2001 From: Pratyush Anand Date: Sun, 3 Jun 2012 19:43:19 +0530 Subject: [PATCH] usb: dwc3: Fix break from cleanup request loop If event status says that its last completed TRB but TRB is still owned by HW then break from the loop, because we are not going to get correct TRB status from trb control/size register.
