[PATCH 4/20] Mark platform device data as const

[PATCH 4/20] Mark platform device data as const

[Jeremy Kerr]

platform_device_add_data()'s data argument can be qualified as const -
the function just copies it to another buffer.

This neatens-up storing other const-ed data there.

Built for powerpc and i386

Ummm, you change the actual function definition here, but you put the
change to the declaration in include/linux/platform_device.h in your
[5/20] patch.  Please redo this patch with the change to the
declaration included.
