We need for the patches to be applied in a timely manner.
Sometimes when there is no real maintainer, that does not happen.
I think the other equally import aspect of maintainership that
drivers/misc (and drivers/char) needs is someone who says no to
stuff that doesn't belong there and helps submitters to find a
proper place where appropriate and to come up with a proper user
interface abstraction.
I'm definitely willing to do that part.
Greg, how about we both formally take ownership of driver/{misc,char}
and you track the patches while I do the bulk of the reviews? You
are definitely better than me with the patch tracking workflow.

That sounds good to me, I'll be glad to collect the patches and push
them to Linus for both of those trees (might as well keep them in the
same git tree, no need to separate them, right?) and I'll rely on you
for review and acking them. Much like I do today for the tty and serial
trees.
I'll go set up the trees locally today and when kernel.org opens back
up, make them public and add them to linux-next.
thanks,
