From d9295532d5725e5926d76470acdfd239c8d2aad3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 30 Aug 2019 08:48:27 +0200 Subject: dma-mapping: remove the dma_declare_coherent_memory export dma_declare_coherent_memory is something that the platform setup code (which pretty much means the device tree these days) need to do so that drivers can use the memory as declared by the platform. Drivers themselves have no business calling this function.
