# \[PATCH 06/61\] gpio: adp5520: Use devm\_gpiochip\_add\_data() for gpio registration - From: Laxman Dewangan \ - Date: 2016-02-22 14:22:08 - List: linux-arm-kernel - Page: https://ratatoskr.run/linux-arm-kernel/2016/02/4690683 - Thread: https://ratatoskr.run/linux-gpio/2016/02/4690677/t.md ```text Use devm_gpiochip_add_data() for GPIO registration and remove the call for gpiochip_remove() from error path. Also remove the need of driver callback .remove.
