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 :)
- prop = of_get_property(op->dev.of_node, "resolution", &size);
+ prop = of_get_property(pdev->dev.of_node, "resolution", &size);
if ((prop) && (size >= sizeof(u32)*2)) {
pdata.xres = prop[0];
pdata.yres = prop[1];
}
- prop = of_get_property(op->dev.of_node, "virtual-resolution", &size);
+ prop = of_get_property(pdev->dev.of_node, "virtual-resolution", &size);
if ((prop) && (size >= sizeof(u32)*2)) {
pdata.xvirt = prop[0];
pdata.yvirt = prop[1];
}
- if (of_find_property(op->dev.of_node, "rotate-display", NULL))
+ if (of_find_property(pdev->dev.of_node, "rotate-display", NULL))
pdata.rotate_screen = 1;
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.
