4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kuangyi Chiang <ki.chiang65@xxxxxxxxx>
commit 17bd54555c2aaecfdb38e2734149f684a73fa584 upstream.
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.
