pch_uart: drop double zeroing
sg_init_table zeroes its first argument, so the allocation of that argument doesn't have to. the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,n,flags; @@ x = - kcalloc + kmalloc_array (n,sizeof(struct scatterlist),flags) ... sg_init_table(x,n) // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> Link: https://lore.kernel.org/r/1600601186-7420-2-git-send-email-Julia.Lawall@inria.fr Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
