# \[PATCH RFT linux-next\] sh: dma-mapping: support debug\_dma\_mapping\_error - From: Shuah Khan \ - Date: 2012-10-26 16:20:09 - List: linux-sh - Page: https://ratatoskr.run/linux-sh/2012/10/3946767 - Thread: https://ratatoskr.run/linux-sh/2012/10/3946767/t.md ```text 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.
