Even though the goal was fairly simple (adding debug to v4l2-ctrls) it ended up spanning this little patchset. The motivation for this cleanup is being able to turn on/off debugging messages in v4l2-ctrls.c, using a knob common to the videodev driver's core. So, in addition to the dev_debug attribute, this series introduces a debug module parameter, and a new debug level, which enables v4l2-ctrl debugging. Having this is quite useful when bringing-up stateless codecs, using the Request API.
