From fabd545c6d27ac1977fe567c43cd4c72fad04172 Mon Sep 17 00:00:00 2001 From: Manish Chopra Date: Fri, 21 Oct 2016 04:43:45 -0400 Subject: [PATCH] qede: Fix incorrrect usage of APIs for un-mapping DMA memory Driver uses incorrect APIs to unmap DMA memory which were mapped using dma_map_single(). This patch fixes it to use appropriate APIs for un-mapping DMA memory. Signed-off-by: Manish Chopra Signed-off-by: Yuval Mintz Signed-off-by: Sudarsana Reddy Kalluru Signed-off-by: David S.
