From 25ea9f2bf5f76082da919f2a91ea8d920932c1da Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Thu, 27 Oct 2016 11:06:44 -0700 Subject: [PATCH] ntb: ntb_hw_intel: init peer_addr in struct intel_ntb_dev The peer_addr member of intel_ntb_dev is not set, therefore when acquiring ntb_peer_db and ntb_peer_spad we only get the offset rather than the actual physical address. Adding fix to correct that.
