What I posted has dynamic_debug.

+#elif defined(CONFIG_DYNAMIC_DEBUG)
+/* dynamic_pr_debug() uses pr_fmt() internally so we don't need it here */
+#define comedi_debug(fmt, ...)                         \
+       dynamic_pr_debug(fmt, ##__VA_ARGS__)

As far as I know, comedi doesn't always take a struct device *.
I believe it's only used when there's a DMA.

In struct comedi_device, there are two struct device *'s.

	struct device *class_dev;
...
	struct device *hw_dev;
