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