[Raag Jadav <raag.jadav@intel.com>]

This series introduces error threshold to drm_ras infrastructure. This
allows user to get and set the error threshold of a specific counter.

Detailed description in commit message and documentation.

v2: Document threshold definition (Riana)
    Return -EOPNOTSUPP on threshold callbacks absence (Riana)
    Cancel and free genlmsg on failure (Riana)
    Document threshold bounds checking responsibility (Riana)
    Add RAS operation status codes (Riana)
    Use goto (Riana)

v3: Move documentation from yaml to rst file (Riana)
    s/value/threshold (Riana)
    Use goto for error handling (Riana)
    Reuse status codes and uapi mapping from counter series (Riana)
    Access request/response counter using local pointer (Riana)
    Mark unused field as reserved (Riana)
    Return -ENOENT on info absence (Riana)

v4: Clarify 0 threshold expectations (Riana)
    Drop redundant wrapping (Riana)
    Make debug logs consistent (Riana)
    Update kdoc (Riana)
