  ata: libata-eh: Fix compilation warning in ata_eh_link_report() (2023-09-28 21:24:18 +0900)

ATA fixes for 6.6-rc4

A larger than usual set of fixes for 6.6-rc4 due to the unexpected
number of fixes needed to address ATA disks suspend/resume issues.
In more details:

 - Add missing additionalProperties on child nodes to the pata-common DT
   bindings (Rob).

 - Fix handling of the REPORT SUPPORTED OPERATION CODES command to
   ignore reserved bits (Niklas).

 - Increase port multiplier soft reset timeout to accomodate slow
   devices and avoid issues on wakeup (Matthias).

 - A couple of minor code fixes to avoid compilation warnings in
   libata-core and libata-eh (me).

 - Many patches from me to address suspend/resume issues, and in
   particular a potential deadlock on resume due to the SCSI disk driver
   resume operation not being synchronized with libata EH port resume
   handling.  This is addressed by changing the scsi disk driver disk
   start/stop control to allow libata to execute disk suspend (spin
   down) and resume (spin up) on its own during system suspend/resume.
   Runtime suspend/resume control remains with the SCSI disk driver.
   Other fixes include:
    - Fix libata power management request issuing to avoid races.
    - Establish a link between ATA ports and SCSI devices to order PM
      operations.
    - Fix device removal to avoid issues with driver rmmod removal.
    - Fix synchronization of libata device rescan and SCSI disk resume
      operation.
    - Remove libsas PM operations as suspend/resume is handled directly
      by the sas controller resume.
    - Fix the SCSI disk driver to not issue commands to suspended disks,
      thus avoiding potential system lock-up on resume.
