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)
Raag Jadav (5):
