Subject: [PATCH] platform/x86: hp-wmi: Ignore Sanitization Mode event
Git-commit: 9ab762a84b8094540c18a170e5ddd6488632c456
Patch-mainline: v5.19-rc5
References: git-fixes

After system resume the hp-wmi driver may complain:
[ 702.620180] hp_wmi: Unknown event_id - 23 - 0x0

According to HP it means 'Sanitization Mode' and it's harmless to just
ignore the event.
