I have applied patch #1 and #2 to my for-next branch. For 3 and4, I'll wait
for Grant's ACK. As for #5, I'd like to get an ACK from the current MSM
maintainers.
Finally, patch #6 will be applied last.

I'm currently moving that away from the mfd_cell structure, in my for-next
branch. mfd_cell now has a platform_data pointer back, and you should use
mfd_get_cell() if you really need to reach the mfd_cell pointer (which you
apparently don't). 
Could you please generate patchs 3 and 4 against this branch ?

Cheers,
Samuel.
