This should have been changelogged!  And a code comment would be good,
too - if it confused me now, it will confused others later.  And such a
code comment will help prevent others from coming in and "cleaning up"
the code later on.

Out-of-tree drivers are unpopular.  Where is this driver, what is its
license and what are the prospects of making it in-tree?

I don't personally have problems with helping out-of-tree drivers but
making it EXPORT_SYMBOL_GPL() would set minds at rest.
