From e728fa18eba8bcbf1f2c4aeb21b6304a16f2f9e4 Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Fri, 23 Nov 2012 14:33:42 -0700 Subject: [PATCH] microblaze: dma-mapping: support debug_dma_mapping_error Add support for debug_dma_mapping_error() call to avoid warning from debug_dma_unmap() interface when it checks for mapping error checked status. Without this patch, device driver failed to check map error warning is generated.
