    Subject[PATCH 4.19 31/48] platform/x86: hp-wmi: Ignore Sanitization Mode event
    Date
    From: Kai-Heng Feng <kai.heng.feng@canonical.com>

    [ Upstream commit 9ab762a84b8094540c18a170e5ddd6488632c456 ]

    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.
