Yes. It is required by "omap_device_build" which in turn calls 
"platform_device_add_data" and copies using "kmemdup" and original
pdata pointer memory will get freed.

It is required by hwmod and not device driver. I can change description.

Thought shorter name is better and still it should be readable.
