[Nouveau] [PATCH 00/53] drm: Convert to platform remove callback returning void

Hello,

this patch series adapts the platform drivers below drivers/gpu/drm
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 (but wrongly) assume any more that there happens some kind of
cleanup later.

Best regards
Uwe
