The patch title should definitely include the name of the driver in question! Otherwise you'll not generally get reviews from the relevant people. Staging:iio:hmc5843 Place driver in sleep mode on error during probe. Also try to cc relevant people and the relevant list. See MAINTAINERS and you'll notice we have both a list and a set of designated reviewers who would like to be cc'd on IIO patches. They may not respond, but if you don't send it to them then they definitely won't!
