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. There are three drivers that got that wrong and potentially returned an error code (caam/jr.c, stm32/stm32-crc32.c, stm32/stm32-cryp.c). These are fixed accordingly. The other drivers could be transformed trivially. See commit 5c5a7680e67b ("platform: Provide a remove callback that returns no value") for an extended explanation and the eventual goal. There are no interdependencies in this series. As there are still quite a few drivers to convert, I'm happy about every patch that makes it in. So even if there is a merge conflict with one patch until you apply (or a different concern that doesn't apply to all patches), please apply the remainder of this series anyhow. I'll come back to the part that you (maybe) skipped at a later point.
