There's a few intermediate dispatcher levels like this, actually.
Lots of video drivers get called behind video_open(), usb drivers from
usb_open(), etc.  Not much to be done but to push things down one level
at a time.

Bisection is going to be problem regardless - if a problem turns up,
it's going to be the chrdev_open() change which gets fingered.  I bet,
though, that it will be a rare BKL-related problem which is reproducible
enough to be easily bisectable.

But, yes, I do need to reorganize the patch series once I'm done adding
on changes.
