[PATCH 0/4] refactor command timeout handling

[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.
