+Subject: firmware: arm_scmi: Fix unused notifier-block in unregister
+To: stable@vger.kernel.org
+Cc: gregkh@linuxfoundation.org, sudeep.holla@arm.com, amitaigottlieb@gmail.com, Amitai Gottlieb <amitaig@hailo.ai>, Dan Carpenter <dan.carpenter@linaro.org>, Cristian Marussi <cristian.marussi@arm.com>
+Message-ID: <20251216115009.30573-1-amitaig@hailo.ai>
+
+From: Amitai Gottlieb <amitaig@hailo.ai>
+
+In scmi_devm_notifier_unregister(), the notifier-block argument was ignored
+and never passed to devres_release(). As a result, the function always
+returned -ENOENT and failed to unregister the notifier.
+
+Drivers that depend on this helper for teardown could therefore hit
+unexpected failures, including kernel panics.
+
+Commit 264a2c520628 ("firmware: arm_scmi: Simplify scmi_devm_notifier_unregister")
+removed the faulty code path during refactoring and hence this fix is not
+required upstream.
+
+Cc: <stable@vger.kernel.org> # 5.15.x, 6.1.x, and 6.6.x
+Fixes: 5ad3d1cf7d34 ("firmware: arm_scmi: Introduce new devres notification ops")
