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

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;
}
...
}
