Hello, this series converts all platform drivers below drivers/mfd to use .remove_new(). 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 resource leaks and/or use-after-free bugs. See commit 5c5a7680e67b ("platform: Provide a remove callback that returns no value") for an extended explanation and the eventual goal. All drivers converted here already returned zero unconditionally in .remove(), so they are converted here trivially. Compared to the (implicit) v1[1] I added two review tags and rebased to today's next/master. Also I failed to Cc: all patches of v1 to lkml.
