From 2c38d6a4e959a88213e24214188e056e5b8cf4c6 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 21 Oct 2021 13:01:46 +0200 Subject: sparc32: remove the call to dma_make_coherent in arch_dma_free LEON only needs snooping when DMA accesses are not seen on the processor bus. Given that coherent allocations are mapped uncached this can't happen for those allocations. Signed-off-by: Christoph Hellwig Tested-by: Andreas Larsson Acked-by: David S.
