Merge tag 'ata-6.1-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata

Pull ata fixes from Damien Le Moal:
 "Several libata generic code fixes for rc5:

   - Add missing translation of the SYNCHRONIZE CACHE 16 scsi command as
     this command is mandatory for host-managed ZBC drives.

     The lack of support for it in libata-scsi was causing issues with
     some passthrough applications using ZBC drives (from Shin'ichiro).

   - Fix the error path of libata-transport host, port, link and device
     attributes initialization (from Yingliang).

   - Prevent issuing new commands to a drive that is in the NCQ error
     state and undergoing recovery (From Niklas).

     This bug went unnoticed for a long time as commands issued to a
     drive in error state are aborted immediately and retried by the
     scsi layer, hiding the useless abort-and-retry sequence"
