[PATCH RFT RESEND linux-next] powerpc: dma-mapping: supportdebug_dma_mapping_error

From: Shuah Khan
Date: Fri Oct 26 2012 - 12:08:20 EST


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.
