Uh, right. Will fix in a second.

I was considering this, but it's a static. And I don't want to change
the fb core, as I'm planning to plug this driver into the "Generic
Panel/Display Framework" [1] that Laurent is working on when it's
available. Then I won't have to hack into the core at all...

Hm, I didn't want to do that, as it's currently just a debug feature -
there is no class symlink to the device available
(Documentation/ABI/testing/sysfs-devices) so there's no universal way of
describing the path to the device.

I'll do my best and post v4 soon.
