I've applied it to the fbdev "for-next" git tree for now to get some compile testing. I hope that's ok for you. Regarding the new "remove_new" struct member I'd prefer a better name but don't have any idea yet...

Ideally we won't have to life with it for long. The eventual plan is to switch back to "remove" once all drivers are converted. So I didn't think intensively about a better name. Did you know that struct i2c_driver has a "temporary" .probe_new() callback since 2016? Best regards Uwe

I'm a bit late, but still Acked-by: Thomas Zimmermann <tzimmermann@suse.de> for the series. Thanks for this cleanup.

I guess this wasn't' done on purpose? Strange. I don't know why I didn't applied those.

We both did some different cleanup, on top of your

If you want to apply it separately, either tell me to post a proper

Hello, this series adapts the platform drivers below drivers/video/fbdev 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. The first patch simplifies the remove callback of one driver to obviously always return zero. After that all drivers are converted trivially to .remove_new().
