Samuel Ortiz 3958fb34ef [IrDA]: irda-usb TX path optimization (was Re: IrDA spams logfiles - since 2.6.19) 
Since we stop using dev_alloc_skb on the IrDA TX frame, we constantly run
into the case of the skb headroom being 0, and thus we call skb_cow for
every IrDA TX frame.
This patch uses a local buffer and memcpy the skb to it, saving us a
kmalloc for each of those IrDA TX frames.
