From: Soren Brinkmann Date: Sun, 4 May 2014 22:42:58 +0000 (-0700) Subject: net: macb: Pass same size to DMA_UNMAP as used for DMA_MAP X-Git-Tag: MMI-PSA29.97-13-9~12250^2~4 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ccd6d0a9104e9075e57fa539ed6bb622b15284d9;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git net: macb: Pass same size to DMA_UNMAP as used for DMA_MAP Just as commit "net: macb: DMA-unmap full rx-buffer" (48330e08fa168395b9fd9f369f06cca1df204361), pass the size that was used for mapping the memory also to the unmap routine to avoid warnings from the DMA_API.
