Jan, thanks a lot for catching this. Have to admit that I didn't
compile it on 64bit.

Acked-by: Alexey Charkov <alchark@...il.com>

Looks like the same would apply to e.g. drivers/clk/samsung/clk.c and
maybe some others... Also, a number of drivers cast OF data from (void
*) to (int) or (unsigned int) - isn't this also problematic on 64bit?

Thanks a lot,
Alexey
