Btw, please run your patches through checkpatch.pl - it does catch
things like that.

Right, this string is user-visible so if we have to be absolutely
honest, the patch does add "functional changes" so you can remove the
statement from the commit message. :)

Btw, what's the story with printk not using KERN_x levels in this file?
Why are we falling back to default printk levels for all printks here
and shouldn't we rather prioritize them by urgency into, say, KERN_ERR,
KERN_INFO, etc?

Those can simply use BIT().

Other than the above nits, a patch which slims down struct names and
makes them more concrete is always welcome :)
