Subject: [PATCH 2/2] xhci: Apply broken streams quirk to Etron EJ188 xHCI host
Date: Wed, 22 May 2024 10:39:17 +0800 [thread overview]
Message-ID: <20240522023918.7613-1-ki.chiang65@gmail.com> (raw)
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.
