It's not about cross-tree conflicts, it's about the fact that my patch is
a fix that needs to be backported to older kernels. It should apply cleanly
to those older kernels if my patch goes in first, but if it is the other way
around I would have to make a new patch for the stable kernels.

Also, the updated changelog in David's patch that sits on top of mine
makes a lot more sense.

If you really don't want to take my patch as part of this, then let me know
and I'll take it through the media subsystem and hope for the best :-)

Regards,
