From 68ba7cb083300409eb92282417db4c179081ade3 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 7 Apr 2015 13:34:01 -0700 Subject: [PATCH] MIPS: DMA: Allow platforms to override only the post DMA hook Instead of having platforms to copy the entirety of mach-generic/dma-coherence.h, check whether these platforms have already defined a plat_post_dma_flush hook, and if not, provide an inline stub.
