From f743106ec140589b45ecc6ff92bacf48a0e26b05 Mon Sep 17 00:00:00 2001 From: Desnes Augusto Nunes do Rosario Date: Fri, 17 Nov 2017 09:09:04 -0200 Subject: [PATCH] ibmvnic: fix dma_mapping_error call This patch fixes the dma_mapping_error call to use the correct dma_addr which is inside the ibmvnic_vpd struct. Moreover, it fixes an uninitialized warning regarding a local dma_addr variable which is not used anymore.
