Subject: [PATCH v3] firmware/arm_sdei: Fix invalid argument to unregister private events.
Date: Thu, 18 Jan 2024 20:20:54 +0000 [thread overview]
Message-ID: <20240118202054.81795-1-ppbuk5246@gmail.com> (raw)
In-Reply-To: <20240118201514.81046-1-ppbuk5246@gmail.com>
To unregister private events in device freeze, it should call
cpuhp_remove_state with sdei_hp_state not sdei_entry_point.
otherwise, it seems to fail on cpuhp_cb_check.
