Variables are supposed to be not aligned at all (in which case you
don't use tabs) or all aligned the same way. In this case you put a
tab before the "*board"; therefore the "*ohci" should line up with it.
No, this isn't an artifact of my email program. They really are not
aligned.

Didn't you say above that this version of the patch removes the call to
ohci_setup()?

Why did you change this? Did we discuss it earlier?
