From ef07387faf33a95e011993200902d490b605407d Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 30 Aug 2013 16:49:20 -0500 Subject: [PATCH] net: calxedaxgmac: read correct field in xgmac_desc_get_buf_len xgmac_desc_get_buf_len appears to have a copy/paste error. flags is the wrong field to read. We should be reading buf_size field. cpu_to_le32 should also be le32_to_cpu. This never really mattered as this function is only used for DMA mapping calls which happen to be nops with coherent DMA.
