[PATCH v2 0/5] mtd: rawnand: sunxi: Fix user data length for H6

[Andre Przywara]

Dario, Michael,

are you going to take those patches eventually, or are they supposed to 
go through the sunxi tree? Somehow patchwork put this on my plate, but 
MAINTAINERS says it's yours.

I will have a final look at those patches, but I think they are fine 
since their counterparts passed the kernel reviews ;-)

Cheers,
Andre
