From 50eacbc8877e725314f140aec091e96c2536d17a Mon Sep 17 00:00:00 2001 From: Ioana Radulescu Date: Tue, 6 Jun 2017 10:00:36 -0500 Subject: [PATCH] staging: fsl-dpaa2/eth: Remove unused fields from priv struct Remove the dpni_id and buffer_layout fields from device's private structure. They're only used at probe so we don't need to store them for further use.
