leds: Convert all platform drivers to return void

2023-11-01T11:28:35+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). All platform drivers below drivers/leds/ unconditionally return zero in their remove callback and so can be converted trivially to the variant returning void.

leds: lgm-sso: Get rid of duplicate of_node assignment

2022-01-12T18:43:15+00:00

GPIO library does copy the of_node from the parent device of the GPIO chip, there is no need to repeat this in the individual drivers. Remove assignment here. For the details one may look into the of_gpio_dev_init() implementation. Call graph: --> sso_gpio_gc_init() --> devm_gpiochip_add_data --> devm_gpiochip_add_data_with_key --> gpiochip_add_data_with_key() --> of_gpio_dev_init() Signed-off-by: Andy Shevchenko Signed-off-by: Pavel Machek
