Subject: [PATCH RFT linux-next] frv: dma-mapping: support debug_dma_mapping_error
Date: Fri, 26 Oct 2012 10:48:13 -0600 [thread overview]
Message-ID: <1351270093.4013.29.camel@lorien2> (raw)
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.
