    	What you can't see just from reading the patch is that in both
    	cases (ehci->itd_pool and ehci->sitd_pool) there are two
    	allocation paths -- the two branches of an "if" statement -- and
    	only one of the paths calls dma_pool_[z]alloc.  However, the
    	memset is needed for both paths, and so it can't be eliminated.
    	Given that it must be present, there's no advantage to calling
    	dma_pool_zalloc rather than dma_pool_alloc.
