Argh, I never sent you my version of that, did I?  Very sorry about
that, I was working on fixing up the device namespace issue first, which
isn't done yet :(

Anyway, my patch that did that is below, feel free to use it or not if
you want.

Yes, the input patch below uses it and I have a block-device patch from
Kay in my tree that Andrew doesn't pull from (as it's usually really
messed up and I know to hide this kind of breakage from him...)

thanks,

Subject: Driver core: convert input core to use struct device

From: Kay Sievers <kay.sievers@vrfy.org>

Converts from using struct "class_device" to "struct device" making
everything show up properly in /sys/devices/ with symlinks from the
/sys/class directory.
