Subject: xhci: flush endpoint context unconditinally
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3f973ee84ef51e448566c08ec5cfe746c9640269;p=qemu.git

xhci: flush endpoint context unconditinally

Not updating the endpoint context in case the state didn't change is
wrong.  Other context fields might have changed, for example the
dequeue pointer in response to a CR_SET_TR_DEQUEUE command.
