Subject: [PATCH RFT RESEND linux-next] powerpc: dma-mapping: support debug_dma_mapping_error
Date: Fri, 26 Oct 2012 10:08:25 -0600 [thread overview]
Message-ID: <1351267705.4013.18.camel@lorien2> (raw)
In-Reply-To: <1351210584.6851.21.camel@lorien2>
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.
