Hi

Some issues have been found with CQE error recovery.  Here are some fixes.

As of V2, the alternative implementation for the patch from Kornel Dulęba:

	https://lore.kernel.org/linux-mmc/e7c12e07-7540-47ea-8891-2cec73d58df1@intel.com/T/#u

is now included, see patch 6 "mmc: cqhci: Fix task clearing in CQE error
recovery")
	
Please also note ->post_disable() seems to be missing from
cqhci_recovery_start().  It would be good if ->post_disable()
users could check if this needs attention.


Changes in V2:

      mmc: cqhci: Fix task clearing in CQE error recovery
            New patch

      mmc: cqhci: Warn of halt or task clear failure
            Add fixes and stable tags


Adrian Hunter (6):
      mmc: block: Do not lose cache flush during CQE error recovery
      mmc: cqhci: Increase recovery halt timeout
      mmc: block: Be sure to wait while busy in CQE error recovery
      mmc: block: Retry commands in CQE error recovery
      mmc: cqhci: Warn of halt or task clear failure
      mmc: cqhci: Fix task clearing in CQE error recovery
