Hello, this series adapts the platform drivers below drivers/gpu/drm/tegra to use the .remove_new() callback. 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. The first two patches are simplifications that make it obvious that all remove callbacks always return zero. After that all drivers can be converted trivially.
