Alan, any objection to just using usb_buffer_alloc() for every driver? Or is that too much overhead?
FWIW, most drivers I've seen in the past hours use a wild mix of kmalloc(), kzalloc(), kcalloc() and usb_buffer_alloc(). That should really be unified.
kmalloc() & friends != usb_buffer_alloc(). They do different things. It makes no sense to unify them. If you really need an ordinary buffer DMA will surely work on, this needs a third primitive.
