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. There were three drivers that did such an early error return in their remove callback. Two of them are fixed, the tegra one is more complicated. I only converted it to return zero (which only suppresses the duplicated warning by the driver core, but doesn't make the resource leak better or worse.) This needs some more attention by someone who understands the driver in question. By changing the remove callback to return void driver authors cannot reasonably assume any more that there is some kind of cleanup later which prevents that such programming errors are introduced in the first place. Note that this series depends on commit 5c5a7680e67b ("platform: Provide a remove callback that returns no value") which is included in v6.3-rc1.
