[PATCH 1/3] MIPS: Remove redundant check in device_tree_init()

[Tiezhu Yang]

In device_tree_init(), unflatten_and_copy_device_tree() checks
initial_boot_params, so remove the redundant check.

drivers/of/fdt.c
void __init unflatten_and_copy_device_tree(void)
{
	int size;
	void *dt;

	if (!initial_boot_params) {
		pr_warn("No valid device tree found, continuing without\n");
		return;
	}
	...
}
