I'm surprised the v4l-dvb tree is carrying this patchset because I haven't
ACKed it. I was planning to take the MFD bits of it and provide Mauro a branch
to pull from (Including the mfd/Kconfig change).
Mauro, could we please go that way instead ? This conflict does not look
pretty to me.

Cheers,
Samuel.
