From 264a2c52062802ea6052011015cb3d919dc14d9f Mon Sep 17 00:00:00 2001 From: Cristian Marussi Date: Mon, 25 Mar 2024 20:46:19 +0000 Subject: firmware: arm_scmi: Simplify scmi_devm_notifier_unregister Unregistering SCMI notifications using the managed devres interface can be done providing as a reference simply the previously successfully registered notification block since it could have been registered only on one kernel notification_chain: drop any reference to SCMI protocol, events and sources. Devres internal helpers can search for the provided notification block reference and, once found, the associated devres object will already provide the above SCMI references for the event.
