Merge tag 'ata-7.1-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linuxHEADmaster

Pull ata fixes from Niklas Cassel:

 - Make sure that the issuing of a deferred non-NCQ command via
   workqueue feature is only used when mixing NCQ and non-NCQ commands
   to the same link (i.e. return value ATA_DEFER_LINK), and nothing
   else. This way we will not incorrectly try to use the feature for
   e.g. PATA drivers

 - The deferred non-NCQ command was stored in a per-port struct. When
   using Port Multipliers with FIS-Based Switching, we would thus
   needlessly defer commands to all other links. Store the deferred QC
   in a per-link struct, such that Port Multipliers with FBS will get
   the same performance as before

 - The issuing of a deferred non-NCQ command via workqueue feature broke
   support for Port Multipliers using Command-Based Switching. The
   issuing of a deferred non-NCQ command via workqueue feature is not
   compatible with the use of ap->excl_link, which PMPs with CBS use for
   fairness (using implicit round robin)
