Well, I don't agree here. The subsystem should be fully specified, at least this
is something I require in pxa, something that is also required in sound/*, etc
... If David doesn't object, I'll keep it that way. As it's his tree, his
decision in the end, so let's have him decide.

May I know where this is documented ?
I'm asking because I didn't find it, because I parsed drivers/net/*.c files, and
the standard kernel comment style was there, ie:
/*
* foo
* bar
*/
I was reusing the previous comment style, but I will change it for the standard
kernel style if you wish.

Ah we had that discussion not very long ago, didn't we ? :)
And I think I'll reuse the "if (ndev->irq < 0) {" solution to be consistent with
myself.
Thanks for the review.
