Zhang, Yanmin b48f5457b4 [PATCH] ipmi: use platform_device_add() instead of platform_device_register() to register device allocated dynamically 
I got below warning when running 2.6.19-rc5-mm1 on my ia64 machine.

The root cause is the device struct is initialized twice.

If the device is allocated dynamically by platform_device_alloc,
platform_device_alloc will initialize struct device, then,
platform_device_add should be used to register the device.

The difference between platform_device_register and platform_device_add is
platform_device_register will initiate the device while platform_device_add
won't.
