From 84aa462e2c2cd1b921f6b8e283f8d41666e02e8e Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 9 Oct 2007 14:17:01 +0100 Subject: [PATCH] [ARM] Rename consistent_sync() as dma_cache_maint() consistent_sync() is used to handle the cache maintainence issues with DMA operations. Since we've now removed the misuse of this function from the two MTD drivers, rename it to prevent future mis-use.
