[PATCH 000/117] media: Convert to platform remove callback returning void

Hello,
this series adapts the platform drivers below drivers/pci 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.
Only three drivers needed some preparation first to make sure they
return 0 unconditionally in their remove callback. Then all drivers
could be trivially converted without side effects to .remove_new().
The changes to the individual drivers are all orthogonal. If I need to
resend some patches because of some review feedback, I'd like to only
send the patches that actually needed changes, so please pick up the
remaining patches that don't need changing to reduce the amount of mail.
Best regards
Uwe
