From: Kuangyi Chiang <ki.chiang65@xxxxxxxxx>
commit 91f7a1524a92c70ffe264db8bdfa075f15bbbeb9 upstream.
As described in commit 8f873c1ff4ca ("xhci: Blacklist using streams on the
Etron EJ168 controller"), EJ188 have the same issue as EJ168, where Streams
do not work reliable on EJ188. So apply XHCI_BROKEN_STREAMS quirk to EJ188
as well.
