[PATCH 00/12] ata: Convert to platform remove callback returning void

[Uwe Kleine-König]

Hello,

this series adapts the platform drivers below drivers/ata 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 touched here returned zero unconditionally in their remove
callback, so they could all be converted trivially to .remove_new().

Once all drivers are converted to .remove_new(), .remove() will be changed to
match today's .remove_new(). Then the drivers here will be converted back
trivially using s/remove_new/remove/. Given the amount of platform drivers this
is still a bit in the future, though.

Best regards
Uwe
