Subject: [PATCH RFT RESEND linux-next] powerpc: dma-mapping: support debug_dma_mapping_error

From: Shuah Khan <[email-masked]>
Date: Fri, 26 Oct 2012 10:08:25 -0600

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.
