ever notice to the following kernel log?
"Device 's3c2440-nand' does not have a release() function, it is
broken and must."
release() function should be implemented in the platform_device.

That's not telling you to provide a release function. The warning is
telling you that a device is being unregistered which doesn't have a
release function.

Consider this point - maybe it doesn't have a release function because
it's not supposed to be unregistered?

This is the cause of the problem. You're registering two dm9000.0
devices. That's illegal, and it then causes all these:

Fix the first problem (which is the real one) and you won't have these
other problems (which aren't actually a problem.)

Heh, well, it is being unregistered, and at that point in time, the
kernel complains.

All kobjects need a release function that actually frees it. If not,
that is a logic bug. Please see the Documentation/kobject.txt file for
details.

The unregistration occurs because platform_register_devices() (which is
used by arch code to register a block of platform devices) undoes its
work if one of the devices fails to register.

I've long since thought, since I created that function, that this probably
isn't desirable behaviour, and it should continue to register as many
devices as it possibly can.

How do you free a statically declared platform device?
