You might use the --strict option for acpi files.

It's generally better not to convert
these printk(KERN_DEBUG uses.

There are behavior differences between
	printk(KERN_DEBUG ...);
and
	pr_debug(...);

The first will always be emitted as long
as the console level is appropriate.

The second depends on a #define DEBUG
before it gets emitted or a kernel
with CONFIG_DYNAMIC_DEBUG enabled and
this entry specifically enabled in the
control file.
