Subject: [PATCH 2/4] xhci: Apply reset resume quirk to Etron EJ188 xHCI host
Date: Tue, 11 Jun 2024 15:06:08 +0300 [thread overview]
Message-ID: <20240611120610.3264502-3-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20240611120610.3264502-1-mathias.nyman@linux.intel.com>
From: Kuangyi Chiang <ki.chiang65@gmail.com>
As described in commit c877b3b2ad5c ("xhci: Add reset on resume quirk for
asrock p67 host"), EJ188 have the same issue as EJ168, where completely
dies on resume. So apply XHCI_RESET_ON_RESUME quirk to EJ188 as well.
