From: FUJITA Tomonori Date: Wed, 26 May 2010 21:44:17 +0000 (-0700) Subject: powerpc: remove unnecessary sync_single_range_* in swiotlb_dma_ops X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=712d3e22a85156c00bd70dc35efe63e6765b122b;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git powerpc: remove unnecessary sync_single_range_* in swiotlb_dma_ops sync_single_range_for_cpu and sync_single_range_for_device hooks in swiotlb_dma_ops are unnecessary because sync_single_for_cpu and sync_single_for_device are used there.
