From: Arnd Bergmann <arnd@xxxxxxxx>
While looking through legacy platform data users, I noticed that
this one could never be used with DT based probing as the
platform_data structure gets overwritten directly after it
is initialized.
There have never been any boards defining the platform_data in
the mainline kernel either, so this driver so far only worked
with patched kernels.
For the benefit of possible downstream users, fix the DT probe
by no longer overwriting the data.
