From 96d9a6eb97d77d6a3768f101f400c42743799bb2 Mon Sep 17 00:00:00 2001 From: Lu Baolu Date: Fri, 7 Apr 2017 17:57:10 +0300 Subject: [PATCH] usb: xhci: fix link trb decoding xhci_decode_trb() treats a link trb in the same way as that for an event trb. This patch fixes this by decoding the link trb according to the spec.
