The patch makes a copy of platform data into driver data, so that any
reference to platform_data after .probe exits can be avoided.

And why is this beneficial? I am of the opinion that platform data should
stay on (and be accessed through a const pointer to ensure that the driver
will not alter it).

Thanks.
