From: Lu Baolu

Hi Mathias,
This patch series is for command timeout refactoring.
Patches
usb: xhci: remove unnecessary second abort try
usb: xhci: remove CRR polling in xhci_abort_cmd_ring()
are follow-ups of your comments of
"remove unnecessary second abort try as a separate patch, send to usb-next"
and
"remove polling for the Command ring running (CRR), waiting for completion
is enough, if completion times out then we can check CRR. for usb-next"
in below discussion thread.

Patches
usb: xhci: add XHCI_MISS_CA_EVENT quirk bit
usb: xhci: warn on command timeout in stopped command ring
are my proposals.
They base on the top of your timeout_race_fixes branch.
