Subject: [PATCH -next] xen-swiotlb: Make two functions static
Date:   Tue, 16 Apr 2019 22:49:50 +0800
Message-ID: <20190416144950.37952-1-yuehaibing@huawei.com>

Fix sparse warnings:

drivers/xen/swiotlb-xen.c:489:1: warning:
 symbol 'xen_swiotlb_sync_single_for_cpu' was not declared. Should it be static?
drivers/xen/swiotlb-xen.c:496:1: warning:
 symbol 'xen_swiotlb_sync_single_for_device' was not declared. Should it be static?
