Ah, ok, thanks.

Did anyone pick it up for mainline already?
Sascha, I didn't see that one in your tree either.

It seems to be pure luck when the patches on the mtd list get picked up.
Most of the time I do not even a reaction from the list or David. I
wonder if someone will beat me up when I take the i.MX nand patches via
my arm tree.

I've put Vladimir's patch to my l2-mtd-2.6.git tree:
http://git.infradead.org/users/dedekind/l2-mtd-2.6.git

which means I'll be pinging David about pulling it. This is all
I can do for you, unfortunately.

Thanks a lot. I really prefer driver patches going over the according
subsystem tree rather then leaking them in from the architecture tree.
