From ccd6d0a9104e9075e57fa539ed6bb622b15284d9 Mon Sep 17 00:00:00 2001 From: Soren Brinkmann <soren.brinkmann@xilinx.com> Date: Sun, 4 May 2014 15:42:58 -0700 Subject: [PATCH] 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.
