Subject: [PATCH 11/21] power: supply: rt5033: Use devm_power_supply_register() helper
Date: Tue, 23 Jan 2024 10:36:43 -0600

Use the device lifecycle managed register function. This helps prevent
mistakes like unregistering out of order in cleanup functions and
forgetting to unregister on error paths.
