From b591741072271f3a7cbf5b976e64ffbfa9a7ce8c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 18 May 2018 15:16:45 +0200 Subject: [PATCH] arc: fix arc_dma_sync_sg_for_{cpu,device} These functions should perform the same functionality as calling arc_dma_sync_single_for_{cpu,device} on each S/G list element. Ensure they actually do that by calling arc_dma_sync_single_for_{cpu,device}. Otherwise we could be passing a different dir argument.
