[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
