[PATCH 08/10] xen/swiotlb: Remove functions not needed anymore.

From: Konrad Rzeszutek Wilk
Date: Mon Sep 10 2012 - 15:59:08 EST


Sparse warns us off:
drivers/xen/swiotlb-xen.c:506:1: warning: symbol 'xen_swiotlb_map_sg' was not declared. Should it be static?
drivers/xen/swiotlb-xen.c:534:1: warning: symbol 'xen_swiotlb_unmap_sg' was not declared. Should it be static?

and it looks like we do not need this function at all.
