I didn't hear anything back about application of this series. Is there a blocker somewhere? Apart from the three preparatory patches that are a precondition to the conversion of the respective drivers, the patches are all pairwise orthogonal. So from my POV the best would be to apply all patches that still apply (which might be all), I will care for the fallout later then. Best regards Uwe

I guess that linux-stable.git is a copy&paste failure (and it's not there). I don't see the series in the master branch of git://linuxtv.org/media_tree.git either. .. a bit later ... ah, it's in git://linuxtv.org/mchehab/media-next.git I guess I was just to quick and probably the series will be included in today's next.

Indeed, I got such a notification on Apr 11. But even if I had that on my radar when asking and considered such notifications reliable in general, I would have asked, as the patches didn't apprear in next up to now. Thanks Uwe
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.
