v2:
* Print the video device node name where possible, in v4l2-ctrls.c,
by passing the struct video_device as a parameter.
* Added a warning to dev_debug attribute store, to warn
the user about V4L2_DEV_DEBUG_CTRL being a no-op for dev_debug.
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.
