The memory of the platform device itself needs to be freed here, otherwise, to do it earlier would cause race conditions and oopses.
I don't do it earlier. I do it later. My platform_device structure is part of my driver's device state structure which is freed explicitly later after the call to platform_device_unregister(). Is that bad?
Look at how the other platform drivers do things.
They do things differently from each other as well as from mine. block/floppy.c, for example, just has a call to complete() there. Anyway, in the latest version of my driver, its platform_device release function finally does something, too: it frees dev->platform_data and pdev->resource just in case something might have materialized there. I hope that's ok. Regards, Tilman -- Tilman Schmidt E-Mail: tilman@imap.cc Bonn, Germany Diese Nachricht besteht zu 100% aus wiederverwerteten Bits.
