I agree with Wolfram here. Debug messages are OK if they are
providing real useful information to a final product.

Besides, as I explained earlier, the patter:

	dev_dbg("timed out")
	return -ETIMEDOUT;

(print a debug but return error) doesn't make much sense.

But, I this is all personal preference. So that I can also leave
it to the specific maintainer.

patch 6 where there are 3 dev_dbg in a row stating the same
thing.

Thanks Dragan and Heiko for your feedback.
