Subject: [PATCH 3/6] reset: lpc18xx: Use devm_register_sys_off_handler()
Date: Wed, 13 Aug 2025 16:41:35 -0500	[thread overview]
Message-ID: <20250813214138.477659-4-afd@ti.com> (raw)
In-Reply-To: <20250813214138.477659-1-afd@ti.com>

Function register_restart_handler() is deprecated. Using this new API
removes our need to keep and manage a struct notifier_block and to
later unregister the handler.
