From 38388301b7b9d2921b58cfa1cd9b14c02d508c63 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Wed, 26 May 2010 14:44:18 -0700 Subject: swiotlb: remove unnecessary swiotlb_sync_single_range_* swiotlb_sync_single_range_for_cpu and swiotlb_sync_single_range_for_device are unnecessary because swiotlb_sync_single_for_cpu and swiotlb_sync_single_for_device can be used instead.
