[PATCH 0/3] spmi: Convert to platform remove callback returning void

this patch series adapts the platform drivers below drivers/spmi
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.
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.
Best regards
