Hi Rob,

When we use script "./scripts/checkpatch.pl" to check a patch, using pr_warning
will produce WARNING:

	WARNING: Prefer pr_warn(... to pr_warning(...
	#22: FILE: drivers/of/fdt.c:428:
	+		pr_warning("End of tree marker overwritten: %08x\n",

So,we should convert pr_warning to pr_warn.


Best Regards
Wang Long
