you cut on this because the line was going over 100 characters? :)

In theory you shouldn't change the print message when doing such
changes and you can still split it as:

		return dev_err_probe(&pdev->dev, ret,
				     "can't get I2C peripheral clock, ret=%d\n",
				     ret);

and you're even within the 80 characters.

Sorry, I missed it in the previous version, mind resending it?
