Compared to the traditional .remove() callback .remove_new() returns no value. This is a good thing because the driver core doesn't (and cannot) cope for errors during remove. The only effect of a non-zero return value in .remove() is that the driver core emits a warning. The device is removed anyhow and an early return from .remove() usually yields a resource leak. By changing the remove callback to return void driver authors cannot reasonably assume any more that there is some kind of cleanup later. All drivers in drivers/spmi returned zero unconditionally in their remove callback, so they could all be converted trivially to .remove_new(). Note that this series depends on commit 5c5a7680e67b ("platform: Provide a remove callback that returns no value") which is included in v6.3-rc1.
