all the above is my start information.I don't know why can't able to

can I do? Thanks
ever notice to the following kernel log?
"Device 's3c2440-nand' does not have a release() function, it is

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?

You never unregister it :)
Otherwise, you will have problems with the reference counting logic, and
you should make it a dynamic device. I really want to move to forcing
all devices to be created dynamically, but the platform devices are the
biggest static device users, so I've not been pushing it very hard, due
to other more pressing issues...

Indeed, and one way to do that is to fix the double-registration of
dm9000.0. Another way to avoid the other complaints is to remove
the unregistration in platform_register_devices().

I agree.

No, because you could have created a platform device with a call to
platform_device_alloc() and then called platform_device_register() and
then later, platform_device_unregister(), right?

No. Sorry, platform_register_devices should've been platform_add_devices().
Please look at that function.
It's used to register an array of static platform devices from architecture
code, as I've said in this thread once already.

Hm, it just calls platform_device_register(), so it's pretty hard to
determine that it's a static device from that function.

I can't think of an easy way to prevent these types of devices from
being removed, other than the existing warnings we have. I'll mull it
over some more and see if I can come up with something in the future.

platform_add_devices() purpose is to allow platforms to bulk-register
their statically declared platform devices. That's what I created it
for.
The easiest solution is to arrange for platform_add_devices() to avoid
unregistering them all if any one fails - eg, we don't particularly want
the platform device for the serial console being unregistered if a
subsequent device fails.
I'd also argue that it should be trying to register as many of the
platform devices as it possibly can, and only warning about devices
it can't register.
Of course, it is possible that it's been used for other purposes by now -
and yes it has:
drivers/mfd/ab3100-core.c: platform_add_devices(ab3100_platform_devs,
drivers/video/backlight/kb3886_bl.c: platform_add_devices(devices, ARRAY_SIZE(devices));
The first one is an oops waiting to happen - it's a modular driver which
has statically allocated platform devices which it registers, and on
removal it just unregisters its I2C driver. Two problems with that:
1. references hanging around after registration and the memory backing
the driver has been unmapped.
2. if two ab3100 devices are present, the same platform device structures
are attempted to be registered more than once.
kb3886_bl.c has the same problem (1) above.
These two drivers need to be converted to use the platform_device_alloc()
et.al. API, which'll then mean that platform_add_devices() goes back to
its original purpose - bulk registering statically allocated platform
devices from arch code.
