I actually wrote a patch getting rid of this ugly thing:

	https://git.linuxtv.org/mchehab/experimental.git/commit/?h=atomisp_v3&id=cf6a15543ace1e99364911c0b7a2f6b8f2f43021

This one was already submitted upstream (not merged yet), but there
are also lots of other patches on my working tree.

I'll try to apply your patch series on it, once I'll be able to
fix a bug with mmap support.

Thanks,
Mauro
