Subject: dma-mapping: remove the dma_declare_coherent_memory export
Git-commit: d9295532d5725e5926d76470acdfd239c8d2aad3
Patch-mainline: v5.4-rc1
References: bsc#1175713

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.
