mfd/bus: sunxi-rsb: Make .remove() callback return void

2021-01-15T13:23:36+00:00

The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. To simplify the quest to make this function return void, let struct sunxi_rsb_driver::remove return void, too. All users already unconditionally return 0, this commit makes this obvious and ensures future users don't behave differently. To simplify even further, make axp20x_device_remove() return void instead of returning 0 unconditionally, too. Signed-off-by: Uwe Kleine-König Reviewed-by: Chen-Yu Tsai Signed-off-by: Lee Jones
