Subject: [PATCH RFT] ARM64: dma-mapping: support debug_dma_mapping_error
Date: Thu, 25 Oct 2012 16:47:00 -0600 [thread overview]
Message-ID: <1351205220.6851.3.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.
