While you're changing these lines, it would be nice to change this
pattern (here and elsewhere) to use of_property_read_u32_array, so that
it's endian-safe and consistent with other devicetree parsing code:
of_property_read_u32_array(pdev->dev.of_node, "phys-size", prop, 2);
It won't read the values if the property data's too short, so that
should be consistent with the existing code.
It would also make the diffstat negative :)

Similarly, this could use of_property_read_bool:
pdata.rotate_screen = of_property_read_bool(pdev->dev.of_node,
"rotate-display");
It won't help the diffstat, but it makes the intent clearer.
Cheers,
Mark.
