[PATCH ath-next v2 0/8] wifi: ath10k: fix recovery and WEDGED failure handling

[Kang Yang]

Recovery failures can consume significant time before the
driver eventually gives up and enters ATH10K_STATE_WEDGED.

This series fixes several issues in the recovery and WEDGED
failure-handling paths, including recovery detection,
recovery time bounding, waiter release, and PCIe error
handling.

Several patches fix specific bugs and therefore carry Fixes
tags. The remaining patches address closely related issues in
the same recovery path because the fixes alone do not fully
resolve the reported failures.

Taken together, the series ensures that recovery either
succeeds or transitions to ATH10K_STATE_WEDGED within a
bounded amount of time, avoids unnecessary waits after
recovery has failed, and reduces the likelihood of watchdog
timeouts on affected platforms.

Google has reported this class of failures for an extended
period, with more than 4000 observed crashes over the last
month.

v2:
- patch 3: also wake wow.wakeup_completed, peer_stats_info_complete and
  wmi.radar_confirm on WEDGED; reinit peer_delete_done before each
  peer delete command.
- patch 5: remove the early-return time_after() branch from the monitor;
  in ath10k_reconfig_complete(), cancel the monitor with
  cancel_delayed_work_sync() before clearing fail_cont_count and
  pending_recovery.
- add SDIO Test-on tag.
