how about a pr_info() or pr_err() here ?? Something like:
pr_err("%s: platform not supported yet\n", __func__);

would be nice to have something like if (cpu_has_iva()) { ... } and move
this check to a later location e.g. on probe(), but this wouldn't prevent
this patch from going in now. Just a suggestion for later improvements.

platform_get_irq(pdev, 0) would look more standard, I think.
