From b66ad1f1aa4dba4e8e242ad8339dd01f4ee77c5e Mon Sep 17 00:00:00 2001 From: Hans Petter Selasky Date: Tue, 23 Aug 2016 13:39:49 +0200 Subject: [PATCH] xhci: Fix remainder field for TR_SETUP completion event. Previously the code would incorrectly report the remainder as 8 bytes. A remainder of 0 bytes should be reported when the SETUP packet is successfully transferred. Found using FreeBSD's XHCI driver.
