Add devm wrappers for the gpiochip_add_data() and gpiochip_remove().
Signed-off-by: Laxman Dewangan
-
Add device managed APIs devm_gpiochip_add_data() and
devm_gpiochip_remove() for the APIs gpiochip_add_data()
and gpiochip_remove().This helps in reducing code in error path and sometimes
removal of .remove callback for driver unbind.Signed-off-by: Laxman Dewangan
-
Base for demv_gpiochip_add_data() and devm_gpiochip_remove().
-
